| 08:21 glance | Hello. |
| 08:22 glance | Im porting my fai-tree to new 3.2 style with unionfs and so on. |
| 08:23 glance | To start adapting installer for ubuntu-gutsy. |
| 08:23 glance | im trying to find which part that should generate the boot-initramfs? |
| 08:24 glance | oz_: are you running some plugin for software-raid or? |
| 08:25 glance | its probably that one thats changes the BOOT_DEVICE when it runs. |
| 08:32 oz_ | glance: year playing with SW_RAID |
| 08:32 glance | then its that guy thats changes your BOOT_DEVICE |
| Mrfai (~lange@suenner.informatik.uni-koeln.de) joined #fai. |
| 08:41 glance | ok. the bug is that the nice "update-initramfs -k all" doesn't bite. |
| 08:41 glance | you needed to use the specific version to trigger it to create a initramfs. |
| 08:41 oz_ | glance: ? i don't understand...? |
| 08:42 glance | oz_: not your bug =) |
| 08:42 glance | oz_: that bug is the one im mucking around with =) |
| meandtheshell (~markus@85.127.114.89) joined #fai. |
| 08:53 glance | ok. the case is: |
| 08:55 glance | in make-fai-nfsroot is update-initramfs diverted and replaced by /bin/true during the creation of the nfsroot and the divert is removed in the end and a initramfs is created. this is probably to speed up the nfs-root create-process so it does't regenerate the initramfs for each package it puts in the nfsroot. |
| 08:56 glance | the problem with this is that when installing a ubuntu kernel package the kernel package postinst-scripts needs to create a initramfs then, or else the initramfs-tools state-system gets confused. |
| 08:57 glance | then there is no state on the initramfs and it won't get created by the last update-initramfs run after the divert is removed. |
| 09:13 zqad | glance: i've got a patch for that |

| 09:15 zqad | but i guess that you've fixed it pretty quick |
| 09:16 glance | its a quite quick hack to fix it but, in that case im more intrested in a solution that fits upstream. |
| 09:18 zqad | i haven't got around examining it, but it seems like removing all update-initramfs works with both ubuntu and debian, so i guess that that works in the upstream. one would just need to check it further |
| 09:18 zqad | i mean, the divert entered between 3.1.8 and 3.2. before that update-initramfs was not diverted to true |
| 09:19 zqad | so it should work anyway :) |
| 09:19 glance | hmm.. |
| 09:19 zqad | the only reason i've found is that it saves time by just running update-initramfs once during make-fai-nfsroot..but i could be wrong. |
| 09:20 glance | ether try to get the flaw in the ubuntu's linux-image postinst fixed. |
| 09:20 zqad | yeah.. |
| 09:20 glance | or maybe do some nifty detection if its a buggy postinst and not divert update-initramfs in that case. |
| 09:21 zqad | that could be a solution..but i'm curious as to why the divert was added in the first place |

| 09:23 glance | divert update-initramfs so it's only called once |
| 09:23 glance | thats the commit-message |
| 09:23 zqad | i apparently suck at the svn-magic..oh, well |
| 09:23 zqad | thanks |
| 09:24 glance | zqad: to young to become a svn-jedi =) |
| 09:24 zqad | :) |
| 09:31 Mrfai | zqad: can you tell me how your patch looks like? |
| 09:33 zqad | Mrfai: it simply don't divert update-initramfs anywhere..but as glance says, that might not be the correct solution |
| 09:54 mikap | Mrfai: I've a basically working grml setup using live-initramfs :) |
| 09:55 mikap | Mrfai: do you have any specific reason why you think fai dirinstall might be better than debian-live for creating the chroot system? (that's definitely not an offend, just because I'm curious :)) |
| 10:03 Mrfai | I did not look deep into debian-live, but using fai dirinstall you can use the nice concepts of FAI classes for creating your chroot environment. |
| 10:05 mikap | right, debian-live provides building chroot as well AFAIK :) hm, one possible benefit of fai dirinstall would be deploying the created ISOs via network, right? :) |
| 10:06 mikap | Mrfai: i'm trying to get fai-client fai-doc fai-server into grml so we can ship that by default, hopefully I can manage that (problem is just disk usage) - looks good now :) |
| 10:07 mikap | anything I could add to the todolist of grml so grml could become a great demo live-cd for FAI? |
| 10:27 Mrfai | I think a special version of grml could become the fai live CD |
| 10:27 Mrfai | This must include the nfsroot, and a partitial mirror of Debian packages |
| 10:27 mikap | ok, but at least as basic build environment it should be sufficient :) |
| 10:28 Mrfai | nfsroot is about 330MB, the partitial mirror around 400 MB |
| 10:28 mikap | I'm working on the grml-live package which includes the fai-setup for building customized grml, as soon as I've first results I'll let you know |
| 10:28 mikap | ok |
| 10:29 Mrfai | fine. Then I will build my own grml CD :-) |
| 10:29 mikap | yeah :) |

| 10:37 oz_ | Mrfai: mikap: sounds great! |
| 10:38 mikap | oz_: the injection by Mrfai on froscon regarding use of live-initramfs was successfull so far, and due to the step-by-step help of Mrfai regarding "build grml-chroot via fai" the autobuild-setup seems to be closer than ever ;) |
| 10:42 lazyb0y | mikap: wow, happy to see you working on that :) |
| Action: lazyb0y is sad for not being able to come to froscon... |
| 10:48 mikap | lazyb0y: I was in your xen-talk but had to notice that it wasn't really you ;) |
| 10:48 mikap | lazyb0y: congrats to your xen-book, it's the best ressource regarding Xen I found and recommend it to everyone asking for Xen-docs :) |
| 10:48 mikap | nice talk by your collegue BTW |
| 10:49 mikap | the best talk I attended on froscon; funny and interesting as well |
| 10:53 lazyb0y | great to hear :) |

| 12:28 glance | Mrfai: the thing is that in ubuntu the newest fai is 3.1.8. |
| 12:28 glance | so the bug isn't introduced yet into ubuntu =) |
| 12:29 glance | thats why i started the discussion here instead, |

| 12:36 Mrfai | how can we detect the the nfsroot is ubuntu and not Debian? Then I could implement a workaround in make-fai-nfsroot. |
| 12:44 h01ger | /etc/debian_version? |
| 12:45 lazyb0y | h01ger: at least on dapper, this still shows: testing/unstable |
| 12:45 lazyb0y | :( |
| 12:46 lazyb0y | maybe by finding that they have upstart instead of init, or something like that |
| 12:53 Mrfai | dpkg -l |grep ubuntu ? |
| 12:54 mikap | not reliable enough IMO |
| 12:54 mikap | at least double-check using uname or something like that |
| 12:54 mikap | doesn't ubuntu have something like /etc/ubuntu_version?! |
| 12:55 h01ger | Mrfai, doesnt work. some debian packages also have ubuntu in the version... |

| 14:09 h01ger | hehe |
| 14:17 lazyb0y | hmm, und kann man nicht einfach in fai.conf sowas DIST= definieren, default ist debian? |
| 14:21 Mrfai | da es nur ein workaround sein soll, wuerde ich lieber eine neue option fuer make-fai-nfsroot einfuehren |
| 14:22 h01ger | find ich auch besser. ist vorallem auch zukunftskompatibler wenns mal ne neue distri gibt |
