| greearb | er, ok..trying again | 00:00 |
|---|---|---|
| greearb | this is just a small little package? | 00:03 |
| greearb | linux-meta-.... ? | 00:03 |
| amitk | greearb: you need to get 'apt-get source linux-image-2.6.24-16-generic' | 00:04 |
| greearb | ok, sorry for my confusion...never used debian so much...downloading that now | 00:05 |
| alex_joni | amitk: you wouldn't be familiar with the livecd by any chance? | 00:07 |
| amitk | greearb: it is confusing even to me sometimes :) | 00:07 |
| alex_joni | I'm looking for the list of packages which get installed by default.. and I can't seem to remember where that was | 00:08 |
| amitk | alex_joni: not particularly and definitely not at 2am :) | 00:08 |
| alex_joni | amitk: same TZ as here ;) | 00:08 |
| amitk | alex_joni: you want to catch cjwatson when he is online | 00:09 |
| greearb | ok, that rules.d looks correct now. It'll take me a few hours to port my patch forward probably... | 00:09 |
| alex_joni | greearb: if you have a single patch file it's not that complicated | 00:10 |
| alex_joni | I would still create a custom flavour (call it greearb) | 00:10 |
| greearb | heh, I have a large number of patches to various parts of the kernel | 00:11 |
| alex_joni | then look at debian/binary-custom.d | 00:11 |
| greearb | ok | 00:11 |
| alex_joni | create a new folder called greearb ;) and put the patches in there.. | 00:11 |
| alex_joni | there's a README which will guide you further | 00:11 |
| greearb | ok, will look at all that...I first need to get the patches so that they will apply to this kernel. | 00:12 |
| alex_joni | (not particularely sure it works with udebs for custom flavours.. but it should afaik) | 00:12 |
| bigcx2 | hey all | 00:26 |
| bigcx2 | i was in here this morning asking about squashfs | 00:26 |
| bigcx2 | i've selected squashfs inside my kernel config | 00:26 |
| bigcx2 | and i've run make-kpkg --append-to-version -squashfs --revision r1 --initrd --config oldconfig kernel_image | 00:27 |
| bigcx2 | but... | 00:27 |
| bigcx2 | when i run update-initramfs -u -v i don't see that it's getting compiled into the kernel | 00:27 |
| bigcx2 | any clues? | 00:27 |
| cjwatson | alex_joni: given a live CD, the simplest way is to look at /casper/filesystem.manifest-desktop | 00:28 |
| alex_joni | cjwatson: I just figured that out.. thanks a lot anyway | 00:28 |
| alex_joni | btw.. I read about 20 minutes of sources (ubiquity) until I reached that conclusion :D | 00:28 |
| cjwatson | alex_joni: of course that's several steps down the chain; in general, it's the dependency-expansion of a bunch of "seeds" | 00:29 |
| alex_joni | cjwatson: short question though.. if I have a package I'm interested in.. I only need to put it in there, not it's dependencies too.. right? | 00:29 |
| cjwatson | no, you need to put everything in there | 00:29 |
| alex_joni | is it me, or the older manifest-desktop didn't have versions? | 00:29 |
| cjwatson | there are ways to automate it (which we use in our own build processes) but they're probably overkill for a one-shot deal | 00:30 |
| alex_joni | yeah, sure.. I only have 1 package + dependencies | 00:30 |
| cjwatson | alex_joni: it's you; the livefs manifests have had versions since they were created | 00:30 |
| cjwatson | (the keyword for the automation in question is "germinate") | 00:30 |
| alex_joni | huh.. germinate? sounds fun | 00:30 |
| cjwatson | sample dependency-expanded lists of packages for Ubuntu are at http://people.ubuntu.com/~ubuntu-archive/germinate-output/ubuntu.hardy/ | 00:30 |
| cjwatson | germinate: vt. to cause seeds to grow | 00:31 |
| alex_joni | cjwatson: cool.. probably extends my knowledge absorbing atm | 00:32 |
| cjwatson | yeah, it's only if you care about how we maintain it | 00:32 |
| cjwatson | very much designed so that ordinary Ubuntu developers can forget about the process and not have to edit lists of packages every time a dependency changes | 00:32 |
| alex_joni | cjwatson: I do this once every couple of years/versions | 00:32 |
| alex_joni | and each time it's more complex (and automated) | 00:33 |
| alex_joni | so I'm not sure if anything I know now will be valid by 10.4 or whatever the next LTS will be :D | 00:33 |
| alex_joni | cjwatson: it looks like quite a lot of work | 00:34 |
| cjwatson | this particular bit of it has not changed a whole lot since 6.06 | 00:35 |
| cjwatson | also, I documented the manifest handling in ubiquity/doc/README a while back | 00:35 |
| cjwatson | yeah, manifest-desktop was created while ubiquity was still called espresso, so pre-release dapper | 00:36 |
| alex_joni | yeah, I noticed a couple of things are the same since dapper | 00:38 |
| alex_joni | (most of the customization part of the LiveCD - squashfs, etc) | 00:38 |
| alex_joni | cjwatson: I notice the docs on the wiki tell one to regenerate the filesystem.manifest then cp that as filesystem.manifest-desktop | 00:42 |
| alex_joni | so I guess that takes care of things | 00:43 |
| greearb | alex_joni, I think I have all of that documented, except for the new kernel...I'll be happy to email it to you... | 00:43 |
| alex_joni | greearb: feel free if you think I can do anything with it :) | 00:45 |
| cjwatson | alex_joni: unwise to cp, would need to cp and remove stuff | 00:46 |
| cjwatson | I'm afraid I haven't been able to keep track of what people have been writing in the wiki - that didn't come from me | 00:46 |
| greearb | there are about 10 wikis, at least, related to this :) | 00:46 |
| alex_joni | cjwatson: well.. they do remove ubiquity | 00:46 |
| * alex_joni meant https://help.ubuntu.com/community/LiveCDCustomization | 00:47 | |
| greearb | most similar to others...and most slightly wrong it seems, depending on your version and what you are trying to do. | 00:47 |
| cjwatson | alex_joni: I would be inclined to manually add the things you want to both, rather than trying to duplicate the list that's removed | 00:47 |
| cjwatson | occasionally I do try to dive in and clean stuff out, but labours of Heracles etc. :-) | 00:48 |
| alex_joni | cjwatson: how about after doing an apt-get update && upgrade.. which just pulled another 450 packages in? | 00:48 |
| * alex_joni doesn't want to think about updating that list by hand | 00:49 | |
| alex_joni | cjwatson: I'll do the cp right now (only temp. version for testing), then after the final hardy CD is released, I'll be careful to add only a couple of packages | 00:50 |
| cjwatson | alex_joni: in that case diff the manifests beforehand and take account of what's removed | 00:51 |
| cjwatson | alex_joni: ubiquity doesn't actually care about the versions in the manifest files - the versions there are just informational | 00:51 |
| cjwatson | so if you literally did upgrade and not dist-upgrade, then it won't actually matter | 00:51 |
| cjwatson | (except cosmetically) | 00:51 |
| alex_joni | heh, ok.. good to know | 00:51 |
| alex_joni | btw, whoever did parallel makesquashfs is my hero | 00:52 |
| alex_joni | Parallel mksquashfs: Using 2 processors | 00:52 |
| greearb | yeah, it only takes maybe 10 minutes now :) | 00:53 |
| alex_joni | cjwatson: thanks again, I'm off to bed now | 00:58 |
| === smb_away is now known as smb_tp | ||
| jdong | alex_joni: yeah, multithreaded squashing is my best friend too | 01:07 |
| bigcx2 | anybody have any clues about the squashfs stuff? | 02:45 |
| greearb | like what? | 02:59 |
| bigcx2 | i'm trying to compile squashfs into a 2.6.20 (ubuntu'ized) kernel | 03:05 |
| bigcx2 | and it works but it never makes into the ramdisk? | 03:05 |
| bigcx2 | doing an update-initramfs -u -v doesn't show it in there | 03:05 |
| bigcx2 | this is for a livecd | 03:06 |
| bigcx2 | so whenever i boot | 03:06 |
| bigcx2 | it fails on mounting the root filesystem | 03:06 |
| bigcx2 | which is obviously squashfs | 03:06 |
| bigcx2 | i'm using make-kpkg with --initrd | 03:08 |
| bigcx2 | if that helps at all | 03:08 |
| bigcx2 | i'm not sure what else to try? | 03:09 |
| greearb | it seems a big pain to get a kernel updated on a live cd image...I'm trying to do the same myself. | 03:09 |
| bigcx2 | apparently | 03:10 |
| bigcx2 | have you gotten it to boot completely? | 03:10 |
| greearb | I'm hacking my patch set now..when it compiles, hopefully I'll get a bit further... I'll write it up then and post it somewhere | 03:10 |
| greearb | not with a custom kernel, but I did with an updated ubuntu kernel | 03:10 |
| greearb | ie, something you can get with apt-get install ... | 03:11 |
| bigcx2 | ahh -- what k version, what ubuntu version? | 03:11 |
| greearb | 7.10 (er, current stable..whatever that is), and 8.04-beta is what I'm working on now. | 03:11 |
| bigcx2 | i c | 03:12 |
| bigcx2 | yea i'm hacking on feisty, which sucks -- the rest of the world has moved on lol | 03:12 |
| greearb | I'm guessing it will all be similar..but will be more sure when I actually get something working :) | 03:13 |
| bigcx2 | hah yea | 03:14 |
| greearb | I got the debian/rules custom-binary-foo to build, but that didn't do udebs. There is a binary-udebs target that seems to be compiling everything from scratch again... Do I need to somehow tell it that it's part of the 'foo' build? | 04:33 |
| bigcx2 | i talked to someone in here this morning that said udebs were only for the alternate install cd | 04:36 |
| greearb | well, I'm trying to build an alternate install cd, so that's probably want I want | 04:36 |
| bigcx2 | oh lol | 04:36 |
| bigcx2 | in that case this might point you in the right direction | 04:37 |
| bigcx2 | http://dsplabs.utt.ro/~juve/blog/index.cgi/01147559232 | 04:37 |
| greearb | yep, found it already..it's for an older release, but some of it might still work | 04:38 |
| bigcx2 | yea..isn't that what you were hoping for earlier :) | 04:39 |

| TomJaeger | Hi. What's the status on bug #124406? | 15:50 |
| ubotu | Launchpad bug 124406 in linux "Keyboard keys get stuck and repeat (Feisty, Gutsy)" [Unknown,Confirmed] https://launchpad.net/bugs/124406 | 15:50 |
| TomJaeger | more specifically, the issue Helge and I are seeing | 15:51 |
| TomJaeger | Also, feel free to try and reproduce it, I don't think it's tied to any particular hardware | 15:53 |
| alex_joni | short question on linux-meta.. trying to build debs for my custom flavour, but somehow the deps are twisted | 15:55 |
| alex_joni | debian/control holds this dependency: linux-headers-$(kernel-abi-version)-rtai | 15:56 |
| alex_joni | however, after the package gets generated I see only linux-headers-2.6.24--rtai (missing the abi '16') | 15:57 |
| alex_joni | (looks the same for the traditional stuff I didn't touch.. like -rt) | 15:58 |
| alex_joni | hmm.. crap.. n/m me.. was missing gawk | 16:02 |

| TomJaeger | bug #124406 anyone? | 16:27 |
| ubotu | Launchpad bug 124406 in linux "Keyboard keys get stuck and repeat (Feisty, Gutsy)" [Unknown,Confirmed] https://launchpad.net/bugs/124406 | 16:27 |
| TomJaeger | I should say that there is a patch and it just needs to be applied | 16:34 |
| alex_joni | what's a reason for an ABI bump? | 17:52 |
| === evand_ is now known as evand | ||
| thom | the ABI changing | 18:00 |
| jdong | thom: you have just made my day :D | 18:03 |
| alex_joni | thom: funny.. | 18:08 |
| alex_joni | is it supposed to happen on released versions (e.g. hardy after it's shipped out) ? | 18:08 |
| cjwatson | it can happen, yes | 18:09 |
| cjwatson | security fixes can change the module ABI from time to time | 18:10 |
| cjwatson | thom's response is actually pretty accurate, but if you want something more detailed, the ABI in question is the interface between the kernel and modules; simplifying massively, if exported functions change their signatures such that modules need to be rebuilt to cope, that's an ABI change | 18:11 |
| alex_joni | cjwatson: I was vaguely familiar with what ABI stands for.. probably my question was bogus :) | 18:11 |
| cjwatson | we've had to change the ABI after release in almost every Ubuntu release so far | 18:12 |
| cjwatson | gutsy has been lucky so far | 18:12 |
| cjwatson | but all of dapper, edgy, feisty have had post-release ABI bumps | 18:12 |
| alex_joni | yeah, but in dapper it wasn't that problematic for me | 18:12 |
| infinity | alex_joni: What are you finding problematic about ABI bumps, post-dapper? | 18:13 |
| alex_joni | infinity: having a custom flavour is what makes it problematic | 18:13 |
| alex_joni | and having to deal with lum, lrm, lbm and meta packages for all that | 18:13 |
| alex_joni | infinity: don't understand me wrong.. what you guys have in place is a great infrastructure.. but it's a bit overengineered for my own needs... | 18:14 |
| infinity | Automation is key. :) | 18:14 |
| alex_joni | infinity: I understand.. but atm I'm doing the automation by hand.. step by step :) | 18:14 |
| infinity | "Oh look, new kernel"; fetch-sources; apply-local-patches; push-big-red-build-button; go-for-coffee. | 18:15 |
| alex_joni | infinity: yeah, but the thing started as a livecd/install environment for our app (which contains kernel modules, and thus kernel-ver dependent) | 18:16 |
| alex_joni | so when ABI changes, and new kernels come out (which through git is quite easy to track), I still have to push a new release on our own software | 18:16 |
| greearb | ok, back to trying to install a custom kernel on a live-cd. Turns out the whole 'udeb' thing was a red herring, it doesn't build initrds for the live-cd. | 19:23 |
| greearb | I do have some good notes for anyone who wants to do that though.... | 19:24 |
| greearb | now, my problem is that I need to compile the headers for my custom kernel. | 19:24 |
| greearb | I got the source: apt-get source linux-ubuntu-modules-2.6.24 | 19:25 |
| greearb | then attempted to build them: | 19:25 |
| greearb | akeroot debian/rules binary-arch arch=i386 flavours=foo | 19:25 |
| greearb | however, the auto-generated debian/control is still relating to generic and not foo. I tried setting debian/d-i/kernel-versions to something with 'foo' in it, but it still does not fully work. | 19:26 |
| greearb | Since the debian/control file is regenerated each time, I can't even run 'sed' tricks to force it right. | 19:26 |
| greearb | suggestions are welcome :) | 19:27 |
| alex_joni | greearb: you need debian/rules debian/control first | 19:35 |
| alex_joni | but that assumes you changed the needed places | 19:36 |
| greearb | can you be any more specific? That doesn't make so much sense :) | 19:36 |
| alex_joni | control.stub | 19:36 |
| alex_joni | you need to add descriptions for you flav | 19:36 |
| alex_joni | then you need to add you falvour to at least rules.d/i386.mk:custom_flavours | 19:37 |
| alex_joni | and to rules.d/0-common-vars.mk:all_custom_flavours | 19:37 |
| greearb | ok, will try that in a sec.. | 19:37 |
| alex_joni | btw, back on breezy I needed two things | 19:38 |
| alex_joni | one is kernel + initrd (you can get those from /boot/ from you regular machine) | 19:38 |
| alex_joni | and the other is the udebs which get loaded lateron | 19:38 |
| alex_joni | brb | 19:38 |
| greearb | don't think I need the udebs, seems that is only for non-live CD builds | 19:39 |
| alex_joni | cjwatson: any ideas why I would get "/init: .: 159: Can't open /scripts/casper" ? | 19:47 |
| alex_joni | (I'll dig for it, but thought you might know without looking..) | 19:47 |
| greearb | seems control.stub might be auto-generated from control.stub.in ? | 19:48 |
| alex_joni | greearb: you're getting warmer :P | 19:49 |
| greearb | no luck | 19:54 |
| greearb | building with: fakeroot debian/rules binary-arch arch=i386 flavours=foo | 19:55 |
| greearb | is that right? | 19:55 |
| alex_joni | nope | 19:56 |
| alex_joni | I use fakeroot debian/rules custom-binary-arch=rtai iirc | 19:56 |
| greearb | for the headers as well? | 19:56 |
| greearb | I'm not building the kernel here...just the headers package | 19:57 |
| alex_joni | I use fakeroot debian/rules custom-binary-rtai | 19:57 |
| greearb | ok | 19:57 |
| alex_joni | that builds image & headers too | 19:57 |
| alex_joni | brb | 19:57 |
| greearb | bleh, I mean modules, not headers. I need the cramfs modules and such | 19:57 |
| greearb | will try poking some more | 19:57 |
| === ogasawara_ is now known as ogasawara | ||
| alex_joni | cjwatson: changing boot option "boot=casper" to "boot=local" makes it go a bit faster .. but it hangs furtheron | 20:08 |
| alex_joni | cjwatson: I also get _tons_ of udevd messages so anything usefull is lost somewhere.. | 20:08 |
| greearb | ahh, by hacking debian/rules to add a fixup script after the debian/control is generated, I seem to be making progress | 20:15 |
| greearb | got udebs for free, too :) | 20:16 |
| greearb | got it to boot! But, seems the gnome toolbar died, so no way I can find to open a bash window to check things in more detail. | 21:19 |
| greearb | not sure if it's a qemu issue or something else | 21:19 |
| alex_joni | cjwatson: probably didn't update initramfs (mkinitramfs -o /initrd.gz 2.6.24-16-rtai) | 21:54 |
| cjwatson | alex_joni: you forgot to install casper before running update-initramfs -u? | 22:23 |
| cjwatson | (or other mkinitramfs method) | 22:23 |
| alex_joni | cjwatson: probably just borked the initramfs (used the install one, not the live-cd generated one) | 22:28 |
| cjwatson | oh, don't do that :) | 22:31 |
| greearb | any idea what the apt-get package for the 'install' desktop icon on the live-cd is called? I managed to uninstall mine somehow... | 22:31 |
| cjwatson | greearb: the desktop file is in ubiquity, but casper is what's responsible for getting it onto the desktop | 22:32 |
| cjwatson | see scripts/casper-bottom/10adduser in the casper source package | 22:32 |
| greearb | ok, I removed a bunch of things...looks like I lost it to a dependency..will try re-adding, or if necessary, start over and be more careful. | 22:33 |
| alex_joni | cjwatson: I just booted the live cd I made :) | 22:36 |
| alex_joni | (this is from the live .. so it works :D) | 22:36 |
| * alex_joni is happy | 22:37 | |
| greearb | congratz! | 22:37 |

| TomJaeger | cool. I should mention that patch fixes a different (but nevertheless very annoying) problem than the original report was about. | 23:35 |
| smb_tp | TomJaeger: I am not sure I can promise much. If I look (not very thouroughly, I admit) at the patch it seems to change the scheduler and feels not like something to do that late in teh cycle. | 23:41 |

| smb_tp | s/taht/that/ (can't type any more) | 23:42 |
| TomJaeger | That's why I bisected the issue right when I noticed how I could reproduce it. | 23:44 |
| TomJaeger | This has been fixed upstream for almost two months now, and it's not like it makes some fundamental changes to the scheduler | 23:46 |
| cjwatson | can I suggest that it might be worth considering this for 8.04.1 rather than 8.04? | 23:47 |
| cjwatson | then there'll be time to find out if it breaks the world when applied to Ubuntu | 23:48 |
| cjwatson | assuming that it goes in early in the 8.04.1 period | 23:48 |
| smb_tp | That would be something I personally would feel better with. But surely I'd like to ask the others, too. | 23:49 |
