superm1evand, i'd think that'd be a neat option to put in the advanced options07:54
evandsuperm1: the UI I was thinking of was automatically backing up the MBR, putting it in a known location, and then adding an option to isolinux/casper that restores the MBR, then looks in fstab and clears the ubuntu partition(s) and, if only one partition is left, resizes it to fill the space.08:04
evandbut perhaps you're looking at it from a different angle?  Can you elaborate?08:04
superm1well UI wise: i was thinking as an option on the last page of ubiquity makes more sense08:05
superm1you know that little advanced button08:05
superm1but easily preseeding the option from one of the menu items in isolinux08:06
evandto back up the mbr, or to do the restore part, or what exactly?08:06
superm1oh yeah that.08:06
superm1to back it up :)08:06
superm1and then for restoring it, put something in friendly-recovery08:06
superm1that can grab it08:06
evandah, indeed08:06
superm1not sure if there is an "easy" way to invoke friendly recovery on the cd at this point though08:07
superm1but that would keep the isolinux menu from getting too cluttered08:07
evandperhaps it could be shoved in one of the submenus, though those are all checkboxes at this point08:07
evandwow, no cjwatson08:08
superm1well thinking about it more, a "recover a broken system" might almost make sense as a main menu item in isolinux08:08
superm1and have this end up as one of the options08:08
evandah, perhaps this can be rolled into the existing recovery plans somehow.08:08
superm1but in some fashion i think this MBR backup to a standard facility is a great idea08:09
evandyeah, other distros have done it for a while so I can't say it's unique08:09
evandbut it was quite the missing piece when advocating Ubuntu (before Wubi came around and provided an easy way to uninstall)08:09
superm1didn't really realize that other distros have had it for a while08:11
superm1i've been entrenched in the ubuntu way of doing things for such a while :)08:11
evandwell, in a limited capacity08:11
evandI believe they just dd the MBR to a file.08:12
evandbut yes, me as well08:12
superm1that's what we're doing for our recovery disks too08:12
superm1to get the utility partition and recovery partition back in shape easily08:12
superm1and properly bootable etc08:12
evandneat08:12
superm1i'll have to bring by and show you some of the things that me and michael got together w/ UDS for it08:13
superm1its all a pretty nice and extensible system now08:13
evandyeah, definitely08:13
evandare you going to be there for the entirety?08:13
superm1yup08:13
evandawesome08:13
superm1coming in saturday or so i think08:13
superm1i'll have to check my flight info08:13
superm1it's a looong flight with 3 layovers i think08:14
evandreally?  I have to go to Atlanta of all places, but that's the only diversion.08:14
superm1oh that's the same thing that cory (_MMA_) got too08:14
superm1i ended up on american airlines (since i like to wrack up miles), so that's why i got all these hops i guess08:14
evandawesome, maybe he'll be on our flight.  For the first time ever I'm sharing a plane with a few coworkers.08:15
superm1oh neat.  did you plan your seats accordingly to power and stuff (http://www.seatguru.com)08:15
evandAh, I try to do that with Contential, but I'm on Delta this time around.08:15
superm1yeah cory is on Delta too08:15
evandgood deal08:16
superm1right before i bought my tickets a coworker was telling me about seatguru over lunch, so i think i might be watching DVDs the whole way or something now :)08:16
evandyeah, it's awesome08:17
evandI actually didn't know you could pick your own seat until this past sprint08:17
evandnow I'm always hunting for a power outlet08:17
superm1well i always try to go the route that i pay out of pocket first08:17
superm1and then get reimbursed08:18
superm1since that means more miles and such08:18
evandah, indeed08:18
evandI'm not buying into the milage game much.  At least on Contential it will take several trips to Europe before I get a free domestic flight.08:18
superm1well i normally wouldn't either, but american gave me a nice 25k starting thing for opening up one of their frequent flyer master cards08:19
evandperhaps I should push for another UDS Australia08:19
superm1and i'm sitting at around 50k now08:19
evandnice08:19
evandI keep getting mailers for that stuff08:19
evandperhaps I should just open the Contential card and not use it08:19
superm1well they have stipulations that you have to spend like 1000 before you get them or something usually08:20
evandah, lame.08:20
superm1well look at it this way though - you will have groceries, gas, and all those regular expenses08:20
superm1that 1000 will come up before you know it08:20
evandyeah, I just hate using a credit card.08:20
evandI find debit cards much easier to manage.08:21
superm1i used to agree with that, until both my mom and i had our CC #'s taken somehow08:21
evandoooouch08:21
superm1and i was really greatful that it was credit cards08:21
superm1so they just wiped the charges08:21
superm1and we were fine08:21
evandyeah, I tend to keep a minimal amount in my checking account for that reason08:21
superm1it was weird though, different states, different card companies, different types of charges, almost every variable different except that it was on the same weekend08:22
evandmy savings and checking accounts with Wamu allow immediate transfers, so its not a big deal to move cash in when I need it08:22
evandweird08:22
superm1yeah that's pretty convenient08:23
superm1ooh yikes.  2:23, i should be in bed.  have a good night :)08:23
evandyou as well08:25
mlindI've got encrypted LVM setup done by Gutsy's alternate installer. I'm unsure how to activate existing crypto and LVM's inside using Hardy alternate installer, is there a guide or wiki entry for this?11:49
cjwatsonI think you should just need to go to "Configure the Logical Volume Manager" and then back out again11:50
mlindcjwatson: There's no such option in the installer menu though11:50
cjwatsonand then set up the partitions as normal11:50
cjwatsonblink11:50
mlindeh, let me rephrase11:50
mlindI probably need to activate the crypto somehow before I can see the LVM inside it11:51
cjwatsonah11:51
cjwatson"Configure encrypted volumes" then11:51
mlindokay, this lets me select the device, but prompts for a "new" password which is bit worrying. is it normal procedure?11:52
cjwatsonI think you need to have at least one partition set to "Use as: physical volume for encryption" first11:52
cjwatsongive me a minute, I haven't actually used this much and am answering by reading the code first11:52
mlindokay, thanks11:52
cjwatsonhmm, it seems to want to erase them by default11:53
cjwatson(except for the way we nobbled the erase)11:53
mlindthat doesn't sound right11:53
cjwatson(but still)11:53
cjwatsonhttp://bugs.debian.org/cgi-bin/bugreport.cgi?bug=45153511:54
ubotuDebian bug 451535 in partman-crypto "debian-installer: allow to 'reuse' encrypted volumes" [Wishlist,Open]11:55
mlindbummer11:55
cjwatsonlinks to http://wiki.debian.org/DebianInstaller/Rescue/Crypto and says you can do that before starting the partitioner11:55
cjwatsonnot pretty, but looks plausible enough11:55
cjwatsonwe have the fix for the bug Frans referred to in partman-lvm11:56
mlindyeah, thanks for the link. looks doable11:56
mlindmaybe this should have been in the release notes11:56
cjwatsonI didn't know about it; but it's quite possible to add to the release notes ;-)11:56
cjwatsonany reason you aren't just upgrading?11:57
mlindyeah, I'd prefer clean install11:57
cjwatsonI'm not going to draft the release notes text right now, but I've added a note to myself to do it11:57
mlindand leave Gutsy as a failsafe11:57
mlindthanks cjwatson11:57
cjwatsonI have been waging a campaign to persuade people that they don't generally need to install from scratch, but if you have a good reason then fair enough11:58
cjwatson(dual-boot is different from installing hardy alongside gutsy, though)11:58
cjwatsonerr ... from installing hardy over the top of gutsy11:58
mlindokay, I've done deboostrapped install from Gutsy -> Hardy, but I'd like to test out what configuration files does the installer write11:59
mlindthat "almost possible" in the Debian bug 451535 sounds worrying. Frans says partman doesn't recognize existing filesystems although those can be mounted.12:03

mlindah, got it. do the magic before starting the partitioner12:09
xivuloncjwatson, evand, had to reopen bug #206113 since a few users reported issues. No logs yet.16:02
ubotuLaunchpad bug 206113 in util-linux "Wubi install cannot create swap space (8.04 Beta) [Regression from alpha 6]" [Undecided,In progress] https://launchpad.net/bugs/20611316:02
cjwatsonxivulon: wouldn't it be clearer at this point to file a new bug, and refer to the old one?16:03
cjwatsonit gets really confusing to keep closing and reopening bugs16:03
xivulonI see, wasn't sure what was the best practice16:03
cjwatsonit's easier to mark a bug as a duplicate if it turns out to be the same as an earlier one, than to split two bugs apart out of one16:04
cjwatsoni.e. Launchpad actually supports the former easily, but doesn't support the latter at all16:04
xivulonok, I'll let it as is for now, once I know more (hopefully will get some logs) will change it as appropriate16:05
xivulonI have been biten by #8497, can we do something with edd=on for point release? add a menu item maybe?16:07
cjwatsonthere *is* a menu item16:16
cjwatsonpress F6 twice at the boot menu16:16
authenticateI meant on the wubi installation menu. That answers it anyway! I will copy what has been done on the live CD!16:18
cjwatsonoh, ok16:18
=== authenticate is now known as xivulon
evandugh, #ubuntu is stressful.16:27
cjwatsonwow, you're keeping up with it?16:29
evandI have wubi and ubiquity on /hilight and am joined to #ubuntu (and was previously in #ubuntu+1)16:30
evandI try to answer questions in there and encourage people to file bugs whenever possible.16:30
evand(installer specific stuff, I don't have the time for general support)16:31
evandit's mostly been "don't use wubi!" and today started the "I hate the new tzmap but wont say more than its annoying"16:32
cjwatsonmy problems in ISO testing were mostly that I found I needed quite quick reactions to get it to scroll to just the right place16:37
cjwatsonnow, I have quite quick reactions, but I can imagine that that might cause problems16:37
evandcan you elaborate on that?  I figured the scroll when on edge took away the need for precision movement.16:39
evandIs it moving too quickly?16:39
cjwatsonyeah, I find it tends to move out from under me too quickly, particularly when scrolling vertically (since the vertical size of the visible map is quite short really)16:40
cjwatsonI noticed you made a change to make the hover areas proportional to the size of the map, which might help16:40
evandhopefully.  I'll have to play with slowing it down.  I also need to stop it from scrolling when the mouse moves out of the map area completely (caused by the delay to zoom out change)16:42
evanddo we have a schedule for 8.04.1 yet?16:42
cjwatsonoh, I meant to talk with you about that :)16:43
* cjwatson tries to find the platform meeting where we talked about 8.04.116:43
cjwatsonok, not a lot of detail there16:45
cjwatsonevand: phone call? still on VoIP?16:45
evandcjwatson: sure, I have my phone back, but let me grab the charger.16:46
evandOne moment.16:46
evand(well, I have my old phone on my number now16:46
evand)16:46
cjwatsonhmm, argh, the USB plug won't go in16:46
cjwatsonI hate computers16:46
cjwatsonah, there, it was just very stiff16:47
evandheh, you picked a hell of a profession then :)16:47
xivulonmost common issues I found so far in wubi: 1) wrong disk order; 2) cannot extract iso (unfinalized medium?); 3) mkswap; 4) video and grub4dos17:12
xivuloncjwatson I am not too convinced about the edd option in menu, most users will "find out" after installation. At that stage it is easier to explain how to edit menu.lst than to rerun the installation with edd=on17:16
xivulonI'd assume that turning it on when more than one disk is detected it's not a good idea correct?17:16
xivulonI could also add a small batch file that edits menu.lst on the windows side17:22
cjwatsonyou might be right about menu.lst (actually, device.map is better)17:40
cjwatsonthe problem with turning on EDD is that it causes some systems to fail to boot17:40
cjwatsonat all17:40
cjwatsonor to have long delays during boot17:40
cjwatsonit's also not nearly so widely implemented as we might like17:40
cjwatsonso it's at best an optional stopgap :-/17:41
cjwatsonthe idea is great, but implementation less so17:41
xivulonyou cannot turn it on post-boot via sysctl or similar I assume17:41
cjwatsonalso, with the way EDD works, it's entirely possible for two disks to have identical signatures if e.g. they're both fresh from the factory17:41
cjwatsonno, you can't, it requires stuff to be done in real mode in early boot17:41
xivulonis device.map used at boot? not sure how that would help since root is already in grub "space" (hdX,Y)17:46
xivulonI was referring about editing menu.lst in post-installation "automatically", which is what I am suggesting users to do at the moment17:47
xivulonhttps://wiki.ubuntu.com/WubiGuide#head-281e2c55090fcd96336e6fe3029fec5aede1a23017:47
cjwatsondevice.map is used by grub-install to map grub devices back and forward so that it can copy the grub image to the right drive17:56
cjwatsonbut I guess you're right that it's important to update groot in menu.lst as well17:56
xivulonI have asked bean123 and tinybit if they have any tip on that, they might have some windows-side tool to get the disk number18:00
xivulonevand any interesting issue people reported on #ubuntu?18:01
cjwatsonit's not a disk number as such18:03
cjwatsonit's a signature of the first bit of the device18:03
xivulondo you mean the X in groot (hdX,Y)?18:04
evandxivulon: there seems to be a lot of resentment towards wubi18:05
evandtrying to get to the bottom of it18:05
xivulonfrom users?18:05
xivulonI cannot connect there18:05
xivulonfrom what I can gather from the forum things are quite okish18:05
evandmostly from people answering questions, from what I can tell18:05
evandthis happened before if you recall, and I talked to the ops and they stopped spreading FUD18:06
evandbut it seems to be regular people who are always in #ubuntu now18:06
cjwatsonxivulon: oh, I see what you mean18:06
cjwatsonxivulon: Windows-side tools are not any more helpful; you need a reliable way to map that to the Linux device name18:06
cjwatsonto my knowledge, EDD is the best we have for that18:06
cjwatsonit's just not very good18:07
cjwatsonit's fundamentally the same kind of problem we have with mapping between Windows devices and Linux devices18:07
cjwatsonreally, it's mapping Linux devices to anything outside Linux, not something to do with the BIOS as such18:07
xivulonevand, is the resentment with the ops?18:07
xivulonfrom the website if most of the bugs are on disk order, it means things are fairly smooth18:08
xivulonsince that is a 1 in 100 type of issue18:08
xivulon(people with multiple disks to begin with)18:08
evandhard to say, I haven't been checking to see who's an op (they're not usually +o)18:08
cjwatsonI have a feeling the resentment is from people who have never used wubi and are not intending to do so18:08
cjwatsonand is therefore unlikely to be due to wubi bugs as such18:08
cjwatsonthey just don't like the idea18:08
xivulonI respect that!18:09
xivulonI also suggest people to go for full installation if they have no issues with ISO and partitioning18:09
evandI fear that people are amplifying cases where it didn't work.  Someone will see someone complain about it not working and then start telling everyone to avoid it because it's horribly broken.18:09
evandbut that's just my guess18:10
cjwatsoncould be18:10
evandI'll prod more and try to get to the bottom of it18:10
xivulonare the ops aware of the wubiguide wiki?18:10
xivulonthe troubleshooting section should take care of the vast majority of issues18:10
evandyes, /msg ubotu wubi18:10
evandif you want that changed, pop into #ubuntu-ops when you can18:11
xivulonI have also noticed that sometimes people blame wubi for general issues18:11
xivulonsuch as acpi or video18:11
xivulonevand cannot reach that (need to edit channel list at home)18:12
bean123hi18:12
xivulonbut they should have a reference to the wubiguide too,18:12
xivulonhi bean123!18:12
xivulonlet me do the introduction18:12
xivulonthis is the dev that maintains grub4dos if you do not him already18:12
xivulonwas extremely helpful on several issues with wubi18:13
bean123you are ago ?18:13
xivulonyes18:13
xivulonago is taken on freenode :(18:13
xivulonand not a good word to highlight...18:13
evandhi bean123, thanks for your hard work on grub4dos!18:14
xivulonas mentioned in the email we were discussing about ways to go about wrong disk order!18:15
xivulonin menu.lst18:15
bean123thanks, :)18:15
xivulonbean123 do you have any tip on that?18:16
bean123i wonder why to use fixed disk name, can you scan it at runtime18:16
xivulonfind --set-root?18:16
bean123any problem ?18:17
xivulonI had that in 7.10 but discarded it in 8.04 since I am not sure that grub (linux) can use it18:17
xivulonand that would have involved more extensive changes in update-grub18:17
xivulonalso can I use relative paths with find --set-root?18:18
xivulonin 7.10 used find --set-root with modified absolute paths ,,,,18:19
xivulonwhich is not an option18:19
bean123you use grub also ?18:19
xivulonwas more to prepare for migrations to real partitions by reducing the delta18:20
xivulonand have a compatible menu.lst to begin with (only requireing groot replacement)18:20
bean123perhaps you can try grub218:20
xivulonnot in 8.0418:21
xivulonwe will probably discuss that at UDS for 8.1018:21
xivuloncjwatson would know more18:21
cjwatsonColin King is looking at grub2; however grub2 has been on our agenda for over two years and has not yet demonstrated the level of stability we would require18:21
cjwatsonfurthermore, grub2 doesn't help here18:21
xivulonbean123 any way to add relative paths to find --set-root18:22
cjwatsonthe fundamental problem remains that of mapping Linux device names to BIOS devices, which none of grub, grub2, or grub2dos can usefully help with18:22
xivulonI think that a new grub4dos build could make 8.04.118:22
cjwatsonin my opinion, we have done the best we are technically able to do in 8.0418:22
xivulonif it fixes the disk order18:22
cjwatsonexcept perhaps for making it easier for users to adjust the order manually when it goes wrong18:23
xivuloncjwatson, grub4dos has this feature whereby it can set the root disk by looking for a file path18:23
xivulonfind --set-root18:23
cjwatsonscanning at run-time *might* be possible, but we would have to leave a UUID-named file around to cope with multiboot systems18:23
xivulonsure that would only replace the root line18:24
xivulonbut...18:24
cjwatsonwe can't just scan for /vmlinuz or whatever18:24
bean123can you be more specific, what function do you want to add to find --set-root18:24
xivulonthe issue is that I need relative paths (if you recall)18:24
xivulonnow they are added via the root command, e.g. root (hd0,2)/ubuntu/disks18:24
xivulonif I use find --set-root, where do I put the relative path?18:25
bean123oh, i see, it shouldn't be difficult18:25
xivulonI think that would make it, and we could look for /ubuntu/disks/boot/vmlinuz maybe?18:26
bean123perhaps i can add a --base parameter to skip the base path18:26
xivulonor --relative anyway something like that18:27
xivuloncjwatson what do you think?18:27
xivulonis it too invasive for 8.04.118:27
xivulon?18:28
cjwatsonup to evand18:33
* evand reads scrollback18:34
evandhrm, is /ubuntu/disks/boot/vmlinuz unique enough?18:41
evandI suppose so18:41
xivulonshould be since I do not allow multiple installations18:43
cjwatsonwell, that's why I was thinking of a UUID-named file somewhere18:43
cjwatsonbut in the case of wubi, sure18:43
xivulonbean123, I guess it would not hert to add the extra find argument if you do not mind18:43
xivulons/hert/hurt/18:43
xivulonrelative path argument I mean18:44
bean123yep18:44
evandcjwatson: indeed, I wasn't sure if his solution adequately addressed the multiboot problem whereas a UUID named file surely would.18:44
xivulonor maybe split the relative path to a separate parameter18:44
xivulonI could create a UUID filename in C\ubuntu\disks\boot18:45
xivulonhopefull users will not delete it18:45
xivulony18:45
xivulonbut then we would need to preseed it correct?18:46
cjwatsonxivulon: no, you could have grub-installer create it and fill it into menu.lst18:48
cjwatsonif the same component does both, preseeding doesn't need to be involved18:48
xivulonof course18:50
xivulonthe above solution (sort of) worked well in 7.10 by the way18:50
xivulonevand /msg ubotu wubi should mention the WubiGuide. Even better: if you have troubles 1) check the troubleshooting section of the WubiGuide, 2) ask in the wubi forum18:52
evandxivulon: can you PM me the exact line you'd like to see and I'll bring it to #ubuntu-ops?18:53
xivuloncould you take care of that?18:54
evandI can, but I'd need to know exactly what you would like ubotu to say when someone requests the wubi factoid.18:55
xivulonevand http://paste.ubuntu.com/8075/18:58
xivulonfeel free to fix my wording18:59
evanda little wordy for IRC, allow me to cut it down a bit19:00
evandthanks19:00
xivulonall yours19:01
xivulonanother small issue19:01
xivulonatm I check for memory >= 256MB19:01
xivulonbut when users have 256 memory that is sometimes reported to be slightly less19:02
xivulonso the check fails and users are confused19:02
evandright, when the video card eats some19:02
xivulonis it ok to lower the limit to 250MB?19:02
evandsounds reasonable19:03
xivulonI'd guess though that then I might get tickets about the installer getting stacked...19:03
evandyou should test it first19:03
evandmake sure it runs comfortably under those conditions19:03
evandthen again, it was pretty close at 25619:03
evandthis might not be a good idea19:04
xivulonwould that be machine specific I guess (video memory)19:04
xivulonok I'll live it at that, I have a skipmemorycheck flag19:04
xivulonand it is in the wubiguide (if only people used it...)19:05
xivulonbean123 thanks in advance :)19:10
bean123:)19:11
xivulonbean123 I am inclined to think that a separate relative path argument might be easier to handle19:15
xivulonso to migrate from loopinstallation to realinstallation I can just delete the #groot line and run update-grub (I guess)19:15
xivulonhmm maybe not19:17
xivulonforget about ^19:17
bean123it seems ok, but i need to discuss with tinybit first19:17
xivulonlets have it inline19:18
bean123ok then19:18
xivulonor we will need to handle 8.04 menu.lst and 8.04.1 menu.lst separately19:18
evandyeah, please remember that 8.04.1 is still under strict rules wrt changes, so shoot for small deltas19:19
xivulonagreed19:19
* xivulon off19:19
bean123just wondering, any plan to use grub2 soon ?19:20
evand13:21:49 < cjwatson> Colin King is looking at grub2; however grub2 has been on our agenda for over two years and has not yet  demonstrated the level of stability we would require19:21
evandbean123: ^ possible, though we haven't had much luck in the past19:21

bean123what's the problem exactly19:22
cjwatsonall sorts, it just hasn't had nearly the degree of hammering that grub has had19:23
cjwatsonno rewrite from scratch is ever half as bug-free as the original until it's had a good period of settling down in wide use; that's why rewrites from scratch are generally a bad idea19:24
cjwatsonand, frankly, we know the bugs that grub has, we don't (for the most part) know the bugs that grub2 has19:24
cjwatsonbut, shrug, last time I tried it didn't even boot. it's probably worth at least looking at again19:24
bean123i think it's working pretty well now, have you checked the latest version19:25
bean123i built a live cd some time ago, you can check it out19:25
bean123http://grub4dos.sourceforge.net/grub2/grub2-2008-04-03.iso.bz219:26
bean123just extract it to C:\, then add this line to boot.ini:19:27
bean123C:\g2ldr.mbr="Start GRUB2"19:27
bean123just like grub4dos19:27
