| cjwatson | anyway, one approach to doing that with d-i would be to preseed the first few steps of the installer (locale/keyboard/network) and put the stuff you actually want to do in preseed/early_command | 12:05 |
|---|---|---|
| cjwatson | maybe terminate it with reboot | 12:05 |
| cr3 | cjwatson: and that can be performed over the net somehow. the purpose for this is to be able to boot the desktop install without having to burn a cd | 12:05 |
| cr3 | cjwatson: if I add a custom d-i, somewhere after network has been detected and drives detected, could I somehow overwrite the installation process altogether, perform those actions I need and then reboot? | 12:08 |
| cjwatson | that would be the procedure I described above | 12:08 |
| cjwatson | well, you might have to force a hardware detection run but in practice disks should have been detected by that pointt | 12:09 |
| cjwatson | point | 12:09 |
| cjwatson | ultimately I'd like to be able to do boot-iso-from-hard-disk using grub2, but note that partitioning gets very difficult when you're relying on an image on the hard disk | 12:11 |
| cr3 | cjwatson: very cool! I can most certainly run all the shell commands I need in that early_command section, thanks! | 12:11 |
| cjwatson | just a warning, I am unlikely to be able to support partitioning problems you run into by this method | 12:11 |
| cr3 | cjwatson: how so? for now, since grub doesn't seem to support iso9660, I'm simply using cp -a into a 800Mb partition at the beginning of the drive | 12:12 |
| cjwatson | the disk is busy and therefore it is not possible to get Linux to re-read the partition table, so new partitions you create won't be usable | 12:12 |
| cjwatson | (until a reboot) | 12:12 |
| cjwatson | this is why both d-i and ubiquity try to avoid having anything mounted on the hard disk | 12:13 |
| cr3 | cjwatson: the new partitions will not be usable to the currently running install, but the d-i script should be able to cp -a onto a partition and then reboot from that partition, right? | 12:14 |
| cjwatson | the device node won't appear until Linux has re-read the partition table | 12:16 |
| cjwatson | so no, not unless the partition existed before you booted | 12:16 |
| cjwatson | or unless you're using a separate hard disk to store the CD image from the one which you're partitioning | 12:17 |
| cr3 | I wonder what tools I could use from the installer to grab the files from an internal server without having to grab the iso locally | 12:19 |
| cr3 | wget -r might work, but I'm not sure if there are symlinks on the installation media and if that would work with wget | 12:19 |
| cr3 | I guess iso9660 is rather limited in feature set so wget -r could potentially work just fine | 12:19 |
| cr3 | I'm not sure if the -r option is supported by the version of wget on busybox | 12:20 |
| cjwatson | it's not | 12:21 |
| cjwatson | honestly, this isn't sounding like a test which will very accurately reproduce a normal installation | 12:22 |
| cjwatson | lifeless did figure out how to NFS-boot the desktop CD; talk to him if you like | 12:23 |
| cr3 | ultimately, the original CD will be extracted integrally onto a partition from which the system will be installed. how is that different from a normal installation? | 12:23 |
| cjwatson | Because the partition table on that disk will be *immutable* while a filesystem is mounted from it. | 12:24 |
| cjwatson | Totally different. The installation really doesn't like unrereadable partition tables. | 12:24 |
| cjwatson | Well, not immutable, but changes won't be reflected until you reboot. | 12:24 |
| cjwatson | this is why e.g. the partitioner has to disable swap before committing partitioning changes | 12:25 |
| cjwatson | but if the partitioner is running off a partition on the hard disk, it won't be able to do that | 12:25 |
| cr3 | doesn't the partitionner run from memory during the installation process? | 12:26 |
| cjwatson | no | 12:27 |
| cjwatson | it's read into memory in order to execute it obviously, but you can't just go unmounting its root filesystem under it! | 12:27 |
| cr3 | there's something I don't understand, I thoutht the root filesystem was an initramfs? | 12:28 |
| cjwatson | if you're booting (a version of) the desktop CD, then the ISO is mounted, a squashfs is loopback-mounted from that, and the eventual root filesystem is a unionfs of that squashfs and a tmpfs | 12:28 |
| cjwatson | the root filesystem is an initramfs in d-i, but that's a very different environment | 12:28 |
| cjwatson | doing the desktop CD with an initramfs / would have vastly increased memory requirements over the existing solution | 12:29 |
| cjwatson | you'd have to unpack the entire CD (effectively) into memory before you could get started | 12:29 |
| cr3 | just in case there's misunderstanding, when I intend the desktop installation to proceed from a partition on the hard drive, I intend it to install onto the rest of the drive and not touch the partition containing the installation media | 12:30 |
| cjwatson | I understand that, but it still won't work. | 12:30 |
| cjwatson | Not unless you use a *separate* drive. | 12:30 |
| cjwatson | A separate partition won't do because it's still inside a partition table which is going to be locked. | 12:30 |
| cr3 | I'm starting to understand the problem now, darn ;( | 12:31 |
| cr3 | cjwatson, I really appreciate you have taken the time to explain this to me, it would've taken me quite a while to figure it out on my own through trial and error | 12:32 |
| cr3 | mostly error :) | 12:32 |
| cjwatson | not a problem, it's not an uncommon line of thought and it's not obvious at first glance why it doesn't work | 12:34 |
| cr3 | I'm gone. g'night and thanks a million! | 12:34 |

| cyp_taf | cjwatson: great | 02:18 |
| cyp_taf | there a website or someting like for know how modify ubiquity | 02:19 |
| cjwatson | no | 02:19 |
| cyp_taf | or a page decribing the internal comportment of ubiquity ? | 02:19 |
| cjwatson | aside from the live CD customization howto somewhere on help.ubuntu.com/community/ | 02:19 |
| cjwatson | there's doc/README in the source package | 02:19 |
| cyp_taf | ok | 02:19 |
| cyp_taf | I have some trouble for use lvm with partman | 02:20 |
| cjwatson | not supported in ubiquity yet. | 02:20 |
| cyp_taf | partman see lvm intruction but dont apply them | 02:20 |
| cjwatson | don't bother trying in ubiquity; it's still a good deal of work. use d-i instead | 02:21 |
| cyp_taf | in facts, my boss ask to me to adapt ubiquity for our custom debian distribution so I can't use d-i directly ... | 02:30 |
| cjwatson | I'm afraid LVM support just isn't there yet | 02:42 |
| cyp_taf | :( | 02:42 |
| cjwatson | it shouldn't be *too* bad to do in the new partitioner, but hooking up the pieces will still be a reasonable amount of code | 02:42 |
| cjwatson | certainly a lot more tractable than in the old partitioner | 02:42 |

| Tux-Rox | While installing Ubuntu in Parallels Desktop on a MacBook, it hangs as the install is finishing, while trying to insmod an IDE controller driver. It never gets to the grub install and even though I can chroot into the file system in the Virtual Machine, grub-install does not see (hd0). Any ideas or command switches that might help? | 03:22 |
| cjwatson | sounds like something that should be fixed in the kernel | 03:28 |
| cjwatson | modprobe hanging => kernel bug | 03:28 |
| === mgalvin [n=mgalvin@ubuntu/member/mgalvin] has joined #ubuntu-installer | ||
| Tux-Rox | cjwatson: Makes sense, except that I have tried not only herd-5and the daily build from the 8th of March, but also herd-1 and 6.10 as well. They all hang at the same spot. It is really odd. I am running ubiquity with the debug switch now to see what happens. | 03:33 |
| Tux-Rox | I feel it might be a Parallels bug, as I once had 6.10 working in an older beta version. I just wanted to get feedback from the installer developers first in case they may have an idea. | 03:35 |
| === stgraber [n=stgraber@ubuntu/member/stgraber] has joined #ubuntu-installer | ||
| Tux-Rox | cjwatson: The exact point at which it freezes the installer is at "Loading module 'aec62xx' for 'IDE chipset support'..." Still seem like a kernel bug? | 03:48 |
| Tux-Rox | Last line in the debug log states: debconf (developer): --> 1 Loading module 'aec62xx' for 'IDE chipset support'... Mar 15 07:45:28 debconf (filter): --> 1 OK | 03:52 |
| Tux-Rox | Last two lines it seems. | 03:53 |
| cr3 | cjwatson: thanks again for the help yesterday, I managed to get the live cd booting over nfs this morning and only two small patches were needed: 1. initramfs-tools to support netboot= option; 2. casper to enable the network for mountroot to work over nfs. | 03:55 |
| cr3 | the patches have already been submitted to Mithrandir and lifeless | 03:56 |
| cr3 | now, I have yet another question: how could I hook into the live cd to run some script once the installer has reached the desktop? | 03:57 |
| cr3 | I could probably modify the squashfs or somesuch, but I really want to have as little impact as possible on the original media | 03:57 |
| cjwatson | Tux-Rox: yes, still seems like a kernel bug | 04:08 |
| cjwatson | ubiquity --debug probably won't help a lot | 04:08 |
| cjwatson | Tux-Rox: I bet if you reboot and run 'sudo modprobe aec62xx' from a shell it'll hang too | 04:08 |
| cjwatson | cr3: tweak casper to dump an appropriate script into /etc/init.d, make it executable, run update-rc.d on it so that it runs late in the boot process? | 04:09 |
| Tux-Rox | cjwatson: I quit out of the installer and first tried insmod. The response was that the module was already loaded. I tried to rmmod and it said that the module was in use by [permanent] , which I expected. I then tried modprobe, and sure enough I had to eventually ctrl-c.... :-( | 04:13 |
| cjwatson | right, that's a sure sign that the kernel has a problem | 04:14 |
| Tux-Rox | I am going to try installing 6.10 once again. | 04:14 |
| cjwatson | mind you I'm surprised you could even ctrl-c | 04:14 |
| cjwatson | Tux-Rox: hang on a sec, there's a workaround at least | 04:15 |
| Tux-Rox | Cool! That is what I was hoping. | 04:15 |
| cjwatson | Tux-Rox: edit /bin/hw-detect as root on the running live CD and look for get_ide_chipset_info | 04:16 |
| cjwatson | Tux-Rox: should be a line that looks like: if [ "$baseidemod" != hpt366 ] ; then | 04:16 |
| cjwatson | Tux-Rox: change that to: if [ "$baseidemod" != hpt366 ] && [ "$baseidemod" != aec62xx ] ; then | 04:16 |
| cjwatson | Tux-Rox: you may have to repeat if other modules hang, and probably reboot after each failure, so I expect it'll be a slow process | 04:17 |
| cjwatson | Tux-Rox: or you could gamble and search for the second instance of get_ide_chipset_info in that file (in the get_manual_hw_info function) and just comment it out by putting a # at the front of the line) | 04:17 |
| Tux-Rox | cjwatson: :-) Thanks! I'll give it a go. | 04:18 |
| cjwatson | thinking about it your disk is probably detected already anyway so commenting that out should be harmless | 04:18 |
| cjwatson | maybe I should just kill off that chunk of code | 04:18 |
| Tux-Rox | It is assumed then that the live-cd puts the /etc scripts in ramdisk? | 04:21 |
| cjwatson | Tux-Rox: I don't understand the question? | 04:31 |
| Tux-Rox | Nevermind, I just typed something random that popped into my head. A bit of a brain fart is all... :-) | 04:32 |
| cjwatson | the whole / on the live session is a unionfs of the squashfs on the CD and a tmpfs | 04:33 |
| cjwatson | so you can write to all of it | 04:33 |
| Tux-Rox | I figured as much, it just took a second after typing the above cryptic question to realize it... :-) | 04:34 |
| cr3 | cjwatson: I discovered that if I just dropped a squashfs in the casper directory, it could automatically be unionfs mounted for me. so, by not having to modify casper scripts, I wouldn't have to rebuild the initrd.gz | 04:48 |
| cr3 | what would be nice is being able to nfs export the union of the live cd iso image and a directory containing my squashfs file, but nfs is broken in regards to unionfs :( | 04:49 |

| cjwatson | why not just comma-separate multiple package names? | 07:03 |
| thom | i have some common packages and some class specific ones | 07:04 |
| cjwatson | you'll need to generate the preseed file in a way that can add to a given line, then | 07:04 |
| cjwatson | or else perhaps use preseed/late_command if you just need to blat in a load of shell | 07:04 |
| thom | yeah, i'm using apt-install in late_command currently, was hoping for a cleaner way | 07:05 |

| joejaxx | cjwatson: the extract-debootstrap script | 11:36 |
| cjwatson | sure, it needs to be on your mirror | 11:36 |
| cjwatson | it doesn't need to be in the d-i initrd | 11:36 |
| cjwatson | extract-debootstrap is just there because debian-cd needs it later on for internal checking purposes | 11:37 |
| cjwatson | (which actually isn't all *that* useful with debootstrap 0.3, but anyway) | 11:38 |
| joejaxx | yeah because debian-cd is not putting the udebs on the cd archive | 11:38 |

| cjwatson | check the stuff in tasks/blah/installer in the scratch directory | 11:47 |
| cjwatson | see if it actually lists any udebs | 11:47 |
| cjwatson | if not, one possibility might be that the mirror you're germinating from doesn't have a proper udeb mirror, or it could be something else weirder | 11:48 |
