| davmor2 | is cdimages.u.c down? | 08:13 |
| cjwatson | 02:39 <MattJ> Is cdimage.ubuntu.com down intentionally? | 09:00 |
| cjwatson | 02:41 <james_w> MattJ: http://91.189.88.34/ should get you there | 09:00 |
| cjwatson | 02:41 <MattJ> james_w: thank you so much :) | 09:00 |
| cjwatson | 02:41 <james_w> only some of the servers behind cdimage are down, so going directly to one that isn't works | 09:00 |
| davmor2 | cjwatson: ta :) Rsync still worked so I got the images I just need to see if they would work :) | 09:17 |
| soren | cjwatson: Are you familiar with di-live? | 09:44 |
| cjwatson | no | 09:44 |
| soren | https://lists.ubuntu.com/archives/ubuntu-server/2008-September/002239.html | 09:44 |
| cjwatson | beyond a general awareness that they've gone down a road I investigated and decided was ultimately doomed | 09:45 |
| soren | Ah :) | 09:45 |
| cjwatson | er, hmm, this doesn't seem to be the same as the live CD stuff based on d-i | 09:45 |
| cjwatson | ok, in this case I'm actually not familiar with it at all, sorry | 09:46 |
| soren | These people have devised a system for creating live CD's for servery kinds of things, and then use this "di-live" thing to run the installer from that running system. | 09:46 |
| soren | It might be worth a look. | 09:46 |
| cjwatson | it looks fairly competently done | 09:47 |
| cjwatson | they've taken quite a similar approach to ubiquity in some ways | 09:48 |
| cjwatson | soren: yeah, I quite like the look of that. Certainly don't reject it out of hand | 09:49 |
| cjwatson | you could invite them in here | 09:49 |
| soren | Certainly. | 09:49 |
| soren | done | 09:52 |
| xivulon | cjwatson would it be feasible to avoid O_DIRECT flags in parted_server? | 10:02 |
| cjwatson | did upstream say they couldn't fix it to actually work? | 10:03 |
| cjwatson | we could make parted fall back from O_DIRECT to !O_DIRECT | 10:04 |
| cjwatson | we can't just drop it - it was added for a reason | 10:05 |
| xivulon | I have asked both szaka and cking but got no reply so far, szaka mentioned in the bug he would add it to the todo list, but I am not sure how long that will take nor if he means honouring O_DIRECT or ignoring O_DIRECT | 10:05 |
| xivulon | fall back will do! | 10:06 |
| cjwatson | that should be straightforward | 10:06 |
| cjwatson | I doubt it matters much whether it's honoured or ignored, for loopback | 10:06 |
| cjwatson | it just needs to be not rejected | 10:07 |
| cjwatson | (at least from parted's point of view; I can see why szaka might feel it's hard to do properly) | 10:07 |
| xivulon | that is what I asked him to do indeed | 10:07 |
| cjwatson | hmm, open(2) documents that some file systems may ignore it | 10:08 |
| cjwatson | sorry, may not implement it - and may fail with EINVAL | 10:08 |
| cjwatson | so maybe working around it in parted is actually the right thing to do | 10:08 |
| xivulon | I have opened bug #269947 | 10:12 |
| cjwatson | something like http://paste.ubuntu.com/47108/ should do it | 10:14 |
| xivulon | looks good, I could test that tonight | 10:18 |
| cjwatson | I'll upload it once I've done some basic testing | 10:19 |
| xivulon | thanks a lot | 10:19 |
| cjwatson | oh, hang on, soren already disabled O_DIRECT altogether | 10:20 |
| cjwatson | soren: would a fallback not be better? | 10:20 |
| davmor2 | Guys give me a ping when you have a working solution that I can test and I'll run it on all versions of windows :) | 10:20 |
| soren | cjwatson: That's what I started out with, but Jim Meyering thought otherwise. | 10:20 |
| soren | Well, actually some dude from SuSE though otherwise, and Jim agreed. | 10:21 |
| cjwatson | really? interesting. so in that case why is the bug still open? :) | 10:21 |
| soren | It's not. | 10:22 |
| * soren whistles | 10:22 | |
| soren | bug 252684 | 10:22 |
| cjwatson | I'll dup, thanks | 10:23 |
| soren | http://lists.alioth.debian.org/pipermail/parted-devel/2008-August/002392.html | 10:23 |
| soren | Sorry about the lack of paperwork. | 10:24 |
| cjwatson | davmor2: today's image should already have Soren's fix | 10:25 |
| davmor2 | cjwatson: cool I'll see how things go then :) | 10:28 |
| davmor2 | xivulon: has the latest wubi been included on the cd yet? | 10:28 |
| xivulon | should be rev 507 | 10:37 |
| xivulon | check also that busybox is the right version (ubuntu6 if I recall correctly) | 10:37 |
| xivulon | yes busybox is there too | 10:38 |
| CIA-59 | ubiquity: cjwatson * r2819 ubiquity/ (apport/ubiquity.py debian/changelog): Add /var/log/casper.log to apport-generated bugs. | 10:41 |
| xivulon | davmor2 all seems in order, please test | 10:42 |
| davmor2 | xivulon: Np's I'll give it a whirl after I get some smoke tests out of the way :) | 10:42 |
| cjwatson | OK. If you have a casper branch (assuming it's just following trunk, and that you don't have any extra revisions on it), then please remove it and check it out again. | 11:31 |
| cjwatson | If you have a non-trivial branch with some unmerged revisions, then please talk to me and we'll get it sorted out | 11:32 |
| davmor2 | cjwatson: I've got issues with the display of the new partition viewer on ubiquity | 11:39 |
| davmor2 | I'll take an image of it after and post it somewhere so you can see what I mean. | 11:41 |
| davmor2 | Hmmm an attempt to configure apt to install additional packages from the CD failed not good :( | 11:52 |
| exodos | hi, im trying to use ubuntu-installer to install hardy on xen domU | 12:06 |
| exodos | (as described in here: http://wiki.debian.org/DebianInstaller/Xen) | 12:06 |
| exodos | the problem is d-i partitioning is not working so I'm looking for a way around it | 12:07 |
| exodos | i started terminal, created partitions and filesystems, and mounted the rootfs on /mnt | 12:08 |
| exodos | is there a way do say d-i that partitioning is already done and it can proceed with base system installation? | 12:09 |
| cjwatson | yes, but with caveats | 12:13 |
| cjwatson | you'll need to mount it on /target, not /mnt | 12:13 |
| cjwatson | you will need to create /target/etc/fstab | 12:13 |
| cjwatson | with that in mind, edit /var/lib/dpkg/info/partman-base.postinst and put 'exit 0' on the second line | 12:14 |
| cjwatson | stuff might go wrong later; this is not a usual path ... | 12:14 |
| exodos | cjwatson: I will check that, thx a lot! | 12:14 |
| === alonswartz is now known as alonswartz_ | ||
| === alonswartz_ is now known as alonswartz | ||
| exodos | are there any plans for future to make d-i working under xen? | 12:27 |
| cjwatson | I thought it was mostly a matter of providing a suitable kernel, but honestly I know very little about it | 12:32 |
| alonswartz | soren: I'm one of the developers behind TurnKey Linux, and the author of di-live. I heard you had some questions so I thought I'd drop in here and say hi. | 12:36 |
| davmor2 | cjwatson: Any idea why if you try installing ubuntu on the live cd directly (rather than through live session) you get the wrong theme? | 12:55 |
| davmor2 | you get the default gnome theme (grey/blue bar etc) | 12:56 |
| davmor2 | xivulon: Yay it worked :) Wubi in XP installed :) | 13:07 |
| xivulon | davmor2 good news :) | 13:13 |
| xivulon | davmor2: couple of things to test a) install a new kernel b) see if suspend/hibernation works | 13:13 |
| xivulon | the latter was disabled, but it __might__ be that the 27 kernel supports suspending to a swap file | 13:14 |
| xivulon | you might to enable hibernation manually or run the underlying commands (let me have a quick look) | 13:15 |
| xivulon | apparently uswsusp can support hibernation to a swap file... | 13:26 |
| cjwatson | davmor2: I've noticed that it seems to be a sort of halfway house (it's not quite the default GNOME theme, I don't think, but it's certainly not ours either), but I don't know why | 13:30 |
| cjwatson | alonswartz: I don't have any specific questions about di-live (I've only had a chance to glance over it), but I noticed there was some inspiration from ubiquity there and it seemed to be rather well-written, so I thought you should be invited in here and that this would be the best place for discussions of it | 13:31 |
| alonswartz | cjwatson: thanks for the invitation, and compliment. | 13:33 |
| cjwatson | also in case there was anything you were stuck on ... | 13:34 |
| alonswartz | Yes, I built heavily on ubiquities design in leveraging d-i code. I originally thought that I would patch ubiquity to support installation from the console, but when I got into the thick of things, I realized that the way to go was modular... | 13:34 |
| cjwatson | the reimplementation of main-menu is a nice idea; I did try that sort of approach originally for oem-config (whose general design grew into ubiquity) but found there were too many crossovers | 13:35 |
| cjwatson | actually, if I were doing ubiquity over again I'd probably take that kind of approach. The current ubiquity main loop came from Guadalinex' code and I was never very happy with it. | 13:35 |
| cjwatson | most of ubiquity's complexity is due to the requirement for a designed UI rather than one generated from the debconf protocol, though. | 13:36 |
| cjwatson | I take it you're just using debconf's dialog interface? | 13:36 |
| alonswartz | yes, i noticed that. I understand that ubiquity came out of the need for a GUI installer, it was just a pity that d-i got wrapped up in that | 13:37 |
| cjwatson | mm, I didn't want to maintain two partitioners. :) | 13:37 |
| alonswartz | hehe... | 13:37 |
| alonswartz | in the long run it would have been easier ;) | 13:37 |
| cjwatson | in fact there were a lot of things where I felt the, uh, business logic was the hard bit and I still feel it's worth not duplicating that | 13:37 |
| cjwatson | plus I like d-i and wanted to make use of it. :) | 13:38 |
| alonswartz | in the future, it might be an idea to consider seperating the GUI code from the d-i code for maintainance and modular reasons | 13:38 |
| alonswartz | re-using d-i code is definately the way to go | 13:39 |
| alonswartz | no point in re-inventing the wheel | 13:39 |
| cjwatson | I'd like to figure out a clearer way to do debconffilter. I think it's the right general approach but it's undeniably hard to program in. Maybe the problem is that it isn't really testable | 13:39 |
| cjwatson | (automatically) | 13:39 |
| cjwatson | or maybe the problem is that most programmers have trouble wrapping their heads around state machines | 13:40 |
| cjwatson | the reason it's interwoven is that there are lots of cases where we need to advance the d-i code just a little bit (rather than by a whole component) in order to figure out how to update the UI | 13:41 |
| cjwatson | the partitioner is the really obvious case, but e.g. keyboard configuration too | 13:41 |
| cjwatson | originally I wanted to do it by way of cdebconf custom widgets | 13:42 |
| alonswartz | its a really interesting concept - creating a debconf filter layer for interception (and possibly injection), but undoubtably complex | 13:46 |
| alonswartz | how did you perform testing, seems to me like a nightmare, especially if you say that auto-testing is out of the questions | 13:49 |
| cjwatson | unfortunately most of the testing I did was system testing, just plug it in, watch the debug information, and see if it's driving it the right way | 13:54 |
| cjwatson | I don't think auto-testing is out of the question, but I'm not very good at building test harnesses | 13:54 |
| cjwatson | the trick is figuring out how to isolate the d-i code, I think | 13:54 |
| cjwatson | and instrument the bits you can't isolate | 13:55 |
| cjwatson | we've managed successful unit testing of some small bits of d-i, like the kernel selection code in base-installer, but nobody's managed to build a test harness for the partitioner yet | 13:55 |
| cjwatson | the usual failure mode with debconffilter is that the d-i code heads off down some path you didn't predict | 13:56 |
| alonswartz | one of the barriers i found when coding di-live, was testing. Most of my testing was done in a segregated chroot, but testing the partitioner was done in a vm. I can only imagine the extra hurdles you had to jump over with the debconf filtering layer... | 13:56 |
| alonswartz | have you thought of any other approaches than the filtering layer ? | 13:59 |
| cjwatson | only custom widgets (i.e. "Type: timezone_map" in a templates file that invokes special debconf plugin, that sort of thing) | 14:01 |
| cjwatson | the problem with that is that it tends to involve substantial changes to the d-i code, and you end up basically copying and pasting chunks of it into the GUI plugin since it needs to do much the same job | 14:01 |
| cjwatson | so in the end I rejected that idea as not viable | 14:02 |
| alonswartz | i have not given GUI interaction much thought, but it seems like an interesting problem to solve, especially the priority of code-reuse | 14:06 |
| alonswartz | when performing the copy of the live filesystem, you use /rofs as the source. From what I understand you do this for "maximum reproducability" - have you considered adding the option of copying the overlay aswell ? | 14:14 |
| alonswartz | overlay = live overlay (with possibly a white or black list) | 14:17 |
| cjwatson | I'm open to suggestions, but I've never seen a way to do it well | 14:24 |
| davmor2 | xivulon: it's todays cd and seems to be the most up-to-date kernel suspend failed to restart | 14:24 |
| cjwatson | mostly people want to copy user-level customisations and such, and those aren't just a matter of copying the overlay in a desktop environment; the username is different, and gconf has a habit of embedding the username into its database as well | 14:24 |
| cjwatson | so it would have to be quite a sophisticated operation | 14:25 |
| cjwatson | it's possible that it would work better in serverland | 14:25 |
| alonswartz | its a feature that i plan on working on in near future for di-live. implementing it in serverland should be easier though. | 14:28 |
| alonswartz | besides for user customizations, did you come across any instability issues regarding certain live content that you *don't* want in the installed system ? | 14:30 |
| cjwatson | well, the thing to be careful of with copying the live overlay is that the user's quite able to change files in e.g. /usr | 14:32 |
| cjwatson | you definitely can't copy the whole overlay, because it includes the customisations made by casper to make the system bootable as a live CD; you don't want those on the installed system | 14:33 |
| cjwatson | so you have to be selective. The easiest way to be selective is just to copy things in /home | 14:33 |
| cjwatson | then what if the user upgraded a package from backports (not that uncommon) on the live CD, and used it? That could easily result in data in /home that the installed system can't read, unless you figure out how to copy everything except for casper's modifications | 14:34 |
| cjwatson | at some point of course you might decide that you don't care, but I didn't want to have to deal with the sort of wildly complicated bug report that this could result in | 14:35 |
| cjwatson | I figured KISS was the way forward :) | 14:35 |
| xivulon | davmor2 did it use to work on your machine/vm in 8.04? | 14:37 |
| alonswartz | i suppose it depends on what the objective of copying the live system state to the hard disk would be. | 14:37 |
| davmor2 | xivulon: can't remember I think it worked on the intel based machine I'll try it on vista after and see | 14:38 |
| alonswartz | in the case of a server type appliance the user might want to test out the system live, maybe configure a database, install or configure a cms or what ever, and then decide thats what he wants. it would then be nice to have the option whether to install the vanilla system, or the customized system | 14:38 |
| cjwatson | right, I agree that the appliance case is very different | 14:39 |
| alonswartz | i suppose its a all or nothing situation, if the user installs packages, customizes configurations, etc. then you have to take all the data across | 14:39 |
| cjwatson | one approach would be to extend casper to be able to reverse all its modifications reliably | 14:39 |
| alonswartz | we have highly customized casper btw, so its not really an issue | 14:40 |
| cjwatson | oh, of course you also have to figure out how to reliably remove di-live itself from the target system; the ease of that depends on how many dependencies it has | 14:40 |
| cjwatson | in ubiquity's case we remove it using python-apt, which is easier since we know the state of the copied filesystem | 14:41 |
| alonswartz | nice catch, its on my todo list... | 14:41 |
| alonswartz | don't you do i diff of the installed packages and the manifest, or something like that? | 14:42 |
| cjwatson | we do a diff of two manifests | 14:43 |
| cjwatson | you could do it even if further packages had been installed if you were careful; only resolve problems by removing packages if those packages are in the diff between the two manifests | 14:44 |
| alonswartz | can you point me to the code that uninstalls ubiquity ? | 14:46 |
| cjwatson | yes, remove_extras in scripts/install.py | 14:50 |
| alonswartz | thanks ;) | 14:51 |
| alonswartz | it seems pretty involved. i was thinking of just passing a list of packages to be removed to apt in the target chroot - what am i missing ? | 14:57 |
| CIA-59 | usb-creator: evand * r13 usb-creator/ (debian/changelog gui/usbcreator.glade scripts/install.py): | 14:58 |
| CIA-59 | usb-creator: Work around a bug in syslinux wherein it can only find the configuration | 14:58 |
| CIA-59 | usb-creator: file for the option labels in the root of the device. | 14:58 |
| cjwatson | alonswartz: robustness - if you do that and just one of them fails, apt may not remove any of the rest, or may leave the system in some kind of half-broken state | 14:59 |
| alonswartz | is their any reason it would fail? the system should be in prestine state, as its a direct copy of /rofs | 15:00 |
| alonswartz | and if it does fail, we could intercept the exception - which would then be a bug, and should be reproducable... | 15:01 |
| alonswartz | cjwatson: unfortunately i gotta run off to a meeting. it was great to finally meet you, and thanks for the informative chat. i'm sure we'll be chatting soon again... | 15:04 |

| Goosemoose | hey cjwatson. im picking up from last week. http://pastebin.com/d14f645a7 shows how the installer is failing when trying to join the domain using my script as part of late_command. the error is: Error: Unable to start daemon [code 0x00080018]. Is there some reason likewise wouldn't start? Should I try starting it manually even though it says it tried to start it? | 17:59 |
| cjwatson | Goosemoose: I'm honestly not sure how much I can help with this. I don't know likewise at all | 17:59 |
| cjwatson | Goosemoose: maybe putting 'mount /proc' at the start of your post_install_tasks script and 'umount /proc' at the end would help; it's possible /proc isn't mounted in the chroot at that point | 18:01 |
| Goosemoose | ok | 18:03 |
| Goosemoose | ill try that | 18:03 |
| Goosemoose | i cant find much on preseed and likewise on the forums at all | 18:03 |
| Goosemoose | I did get this as well: Sep 12 22:18:03 log-output: /target/etc/nsswitch.conf: No such file or directory | 18:03 |
| Goosemoose | as I was trying to remove the nsswitch.conf so I could wget a new copy. Does this just mean it hadn't been created by that point in the install process? | 18:04 |
| cjwatson | did you put /target/etc/nsswitch.conf in your post_install_tasks script, rather than /etc/nsswitch.conf? | 18:04 |
| Goosemoose | yes | 18:04 |
| cjwatson | you shouldn't have done that | 18:04 |
| cjwatson | put it back to /etc/nsswitch.conf | 18:04 |
| Goosemoose | oh, I thought you said everything was installed in the /target dir until reboot | 18:04 |
| Goosemoose | my mistake | 18:04 |
| cjwatson | and I also said that putting 'chroot /target' in front of the call to post_install_tasks was all you needed, and said several times that you shouldn't add references to /target to post_install_tasks | 18:04 |
| Goosemoose | ahh , very true. sorry about that | 18:05 |
| cjwatson | 'chroot /target /post_install_tasks' means, roughly, that everything in the post_install_tasks is implicitly done with reference to /target | 18:05 |
| cjwatson | so you don't need to, and shouldn't, refer to /target in there | 18:05 |
| Goosemoose | yeah i forgot I had changed to do that | 18:05 |
| cr3 | what's that kernel parameter I could pass during installation of the alternate to interrupt the installation at some point, perhaps around early command? | 19:16 |
| cjwatson | I don't know of such a thing. You could make your early_command return an error :) | 19:17 |
| cr3 | cjwatson: hm, I thought I recalled something of way to interrupt the installer but I guess there's not much use case for that... and there's an easy workaround as you pointed out :) | 19:21 |
| cr3 | cjwatson: I wrote a nifty little program in C this weekend to check the log file for patterns which I will wrap in a shell script to test for specific phases of the installation | 19:23 |
| cr3 | I'm quite anxious to try it out | 19:23 |
| Goosemoose | cjwatson, it looks like i got it to join the domain, who knows more about likewise though because it through a bunch of pam errors | 21:14 |
| Goosemoose | and wont let me login as a domain user | 21:14 |
| cr3 | might someone have a good example of a project using autotools and packaged using cdbs both as a deb and a udeb? | 21:44 |
| hardwire | cr3: wireless-tools ? | 22:03 |
| hardwire | maybe not | 22:04 |
| cr3 | hardwire: heh, doesn't use autotools nor cdbs :) | 22:04 |
| hardwire | I'm not on my game today. | 22:04 |
| hardwire | can't you query the source package lists via those fancy dpkg query tools? | 22:04 |
| hardwire | or grep | 22:05 |
| hardwire | cat /var/lib/apt/lists/*Sources | grep cdbs -B 10 | grep autotool -B 10 | grep Package | 22:06 |
| hardwire | maybe I'm insane | 22:06 |
| hardwire | I'd like to think it's a possibility | 22:06 |
| cr3 | for some reason, DEB_DH_INSTALL_SOURCEDIR only applies to the deb which calls dh_install with --sourcedir but that argument is not used for the udeb | 22:06 |
| cr3 | ok, so cdbs seems to be borked when using DEB_DH_INSTALL_SOURCEDIR. using DEB_DH_INSTALL_ARGS := --sourcedir=$(DEB_DESTDIR) seems to work | 22:11 |
| Goosemoose | cjwatson: Sep 15 17:38:12 log-output: /post_install_tasks: 14: unmount: not found | 22:17 |
| Goosemoose | cjwatson: looks like unmount /proc isn't valid. i don't see an error for the mount which is strange | 22:17 |
| evand | Goosemoose: shouldn't that be umount? | 22:27 |
| Goosemoose | evand, that might explain it ;) | 22:27 |
| Goosemoose | thanks | 22:27 |
