| [00:00] <greearb> er, ok..trying again | |
| [00:03] <greearb> this is just a small little package? | |
| [00:03] <greearb> linux-meta-.... ? | |
| [00:04] <amitk> greearb: you need to get 'apt-get source linux-image-2.6.24-16-generic' | |
| [00:05] <greearb> ok, sorry for my confusion...never used debian so much...downloading that now | |
| [00:07] <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 :) | |
| [00:08] <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 ;) | |
| [00:09] <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... | |
| [00:10] <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) | |
| [00:11] <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 | |
| [00:12] <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) | |
| [00:26] <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 | |
| [00:27] <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? | |
| [00:28] <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 | |
| [00:29] <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? | |
| [00:30] <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/ | |
| [00:31] <cjwatson> germinate: vt. to cause seeds to grow | |
| [00:32] <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 | |
| [00:33] <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 | |
| [00:34] <alex_joni> cjwatson: it looks like quite a lot of work | |
| [00:35] <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 | |
| [00:36] <cjwatson> yeah, manifest-desktop was created while ubiquity was still called espresso, so pre-release dapper | |
| [00:38] <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) | |
| [00:42] <alex_joni> cjwatson: I notice the docs on the wiki tell one to regenerate the filesystem.manifest then cp that as filesystem.manifest-desktop | |
| [00:43] <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... | |
| [00:45] <alex_joni> greearb: feel free if you think I can do anything with it :) | |
| [00:46] <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 | |
| [00:47] * 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 | |
| [00:48] <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? | |
| [00:49] * alex_joni doesn't want to think about updating that list by hand | |
| [00:50] <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 | |
| [00:51] <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 | |
| [00:52] <alex_joni> btw, whoever did parallel makesquashfs is my hero | |
| [00:52] <alex_joni> Parallel mksquashfs: Using 2 processors | |
| [00:53] <greearb> yeah, it only takes maybe 10 minutes now :) | |
| [00:58] <alex_joni> cjwatson: thanks again, I'm off to bed now | |
| === smb_away is now known as smb_tp | |
| [01:07] <jdong> alex_joni: yeah, multithreaded squashing is my best friend too | |
| [02:45] <bigcx2> anybody have any clues about the squashfs stuff? | |
| [02:59] <greearb> like what? | |
| [03:05] <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 | |
| [03:06] <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 | |
| [03:08] <bigcx2> i'm using make-kpkg with --initrd | |
| [03:08] <bigcx2> if that helps at all | |
| [03:09] <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. | |
| [03:10] <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 | |
| [03:11] <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. | |
| [03:12] <bigcx2> i c | |
| [03:12] <bigcx2> yea i'm hacking on feisty, which sucks -- the rest of the world has moved on lol | |
| [03:13] <greearb> I'm guessing it will all be similar..but will be more sure when I actually get something working :) | |
| [03:14] <bigcx2> hah yea | |
| [04:33] <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? | |
| [04:36] <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 | |
| [04:37] <bigcx2> in that case this might point you in the right direction | |
| [04:37] <bigcx2> http://dsplabs.utt.ro/~juve/blog/index.cgi/01147559232 | |
| [04:38] <greearb> yep, found it already..it's for an older release, but some of it might still work | |
| [04:39] <bigcx2> yea..isn't that what you were hoping for earlier :) | |

| [15:50] <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 | |
| [15:51] <TomJaeger> more specifically, the issue Helge and I are seeing | |
| [15:53] <TomJaeger> Also, feel free to try and reproduce it, I don't think it's tied to any particular hardware | |
| [15:55] <alex_joni> short question on linux-meta.. trying to build debs for my custom flavour, but somehow the deps are twisted | |
| [15:56] <alex_joni> debian/control holds this dependency: linux-headers-$(kernel-abi-version)-rtai | |
| [15:57] <alex_joni> however, after the package gets generated I see only linux-headers-2.6.24--rtai (missing the abi '16') | |
| [15:58] <alex_joni> (looks the same for the traditional stuff I didn't touch.. like -rt) | |
| [16:02] <alex_joni> hmm.. crap.. n/m me.. was missing gawk | |
| === elmargol_ is now known as elmargol | |
| [16:27] <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 | |
| [16:34] <TomJaeger> I should say that there is a patch and it just needs to be applied | |
| [17:52] <alex_joni> what's a reason for an ABI bump? | |
| === evand_ is now known as evand | |
| [18:00] <thom> the ABI changing | |
| [18:03] <jdong> thom: you have just made my day :D | |
| [18:08] <alex_joni> thom: funny.. | |
| [18:08] <alex_joni> is it supposed to happen on released versions (e.g. hardy after it's shipped out) ? | |
| [18:09] <cjwatson> it can happen, yes | |
| [18:10] <cjwatson> security fixes can change the module ABI from time to time | |
| [18:11] <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 :) | |
| [18:12] <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 | |
| [18:13] <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 | |
| [18:14] <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 :) | |
| [18:15] <infinity> "Oh look, new kernel"; fetch-sources; apply-local-patches; push-big-red-build-button; go-for-coffee. | |
| [18:16] <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 | |
| [19:23] <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. | |
| [19:24] <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. | |
| [19:25] <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 | |
| [19:26] <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. | |
| [19:27] <greearb> suggestions are welcome :) | |
| [19:35] <alex_joni> greearb: you need debian/rules debian/control first | |
| [19:36] <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 | |
| [19:37] <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.. | |
| [19:38] <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 | |
| [19:39] <greearb> don't think I need the udebs, seems that is only for non-live CD builds | |
| [19:47] <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..) | |
| [19:48] <greearb> seems control.stub might be auto-generated from control.stub.in ? | |
| [19:49] <alex_joni> greearb: you're getting warmer :P | |
| [19:54] <greearb> no luck | |
| [19:55] <greearb> building with: fakeroot debian/rules binary-arch arch=i386 flavours=foo | |
| [19:55] <greearb> is that right? | |
| [19:56] <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? | |
| [19:57] <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 | |
| === ogasawara_ is now known as ogasawara | |
| [20:08] <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.. | |
| [20:15] <greearb> ahh, by hacking debian/rules to add a fixup script after the debian/control is generated, I seem to be making progress | |
| [20:16] <greearb> got udebs for free, too :) | |
| [21:19] <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 | |
| [21:54] <alex_joni> cjwatson: probably didn't update initramfs (mkinitramfs -o /initrd.gz 2.6.24-16-rtai) | |
| [22:23] <cjwatson> alex_joni: you forgot to install casper before running update-initramfs -u? | |
| [22:23] <cjwatson> (or other mkinitramfs method) | |
| [22:28] <alex_joni> cjwatson: probably just borked the initramfs (used the install one, not the live-cd generated one) | |
| [22:31] <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... | |
| [22:32] <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 | |
| [22:33] <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. | |
| [22:36] <alex_joni> cjwatson: I just booted the live cd I made :) | |
| [22:36] <alex_joni> (this is from the live .. so it works :D) | |
| [22:37] * alex_joni is happy | |
| [22:37] <greearb> congratz! | |
| [22:40] <greearb> here are my notes. This worked for me, though I've yet to run it all from a clean install, so I might be missing a few things yet. | |

| [23:35] <TomJaeger> cool. I should mention that patch fixes a different (but nevertheless very annoying) problem than the original report was about. | |
| [23:41] <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. | |
| [23:42] <smb_tp> s/and feels/and taht feels/ | |
| [23:42] <smb_tp> s/taht/that/ (can't type any more) | |
| [23:44] <TomJaeger> That's why I bisected the issue right when I noticed how I could reproduce it. | |
| [23:46] <TomJaeger> This has been fixed upstream for almost two months now, and it's not like it makes some fundamental changes to the scheduler | |
| [23:47] <cjwatson> can I suggest that it might be worth considering this for 8.04.1 rather than 8.04? | |
| [23:48] <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 | |
| [23:49] <smb_tp> That would be something I personally would feel better with. But surely I'd like to ask the others, too. | |
