Installing Debian Squeeze (i386) - No $HOSTNAME set
Hallo, just tried to install current Debian Squeeze (i386) using fai 3.4.2 with partly success. (Installation with Fai is quite new to me, so maybe I should have tried lenny first - but however I need a squeeze installation.) So here is what I have done: - Downloaded and installed fai-packages from http://people.debian.org/~mika/fai/release/ - Typical commands: fai-setup fai-mirror /srv/fai/mirror make-fai-nfsroot; fai-cd -f -m /srv/fai/mirror /mnt/hgfs/TEMP/fai-test1.iso Just used demo config (except some changes for my local mirror). - Booted the fai-cd - Selected gnomehost (demohost didn't work either) After installation finished only the base system (FAIBASE and DHCPC) was there, no GNOME and no GERMAN as expected. The login prompt on the second terminal is "root@(none)". No hostname set, no network configuration, "cat /proc/cmdline" says: BOOT_IMAGE=/boot/vmlinuz boot=live FAI_FLAGS=verbose,createvt FAI_ACTION=install ip=192.168.1.1:eth0:of hostname=gnomehost" Guess somehow these settings should be passed to the installation system. That seems to be the reason why only FAIBASE was installed (script "50-host-classes"). Regards Karl
Re: Installing Debian Squeeze (i386) - No $HOSTNAME set
Perhaps stupid question but you did not mention that... did you boot the machine at the end of installation? If yes, are you sure your booted the installed system, rather than the installation system again? It sounds like you are still at the prompt of the installation system, not your installed system.

After reboot the prompt is still "root@(none)". IMHO the selection of package classes works like this: - In Grub menu.lists there is some entry like: ... hostname=gnomehost - The installation system somehow detects this and should set the hostname <== This step fails - The script "/var/lib/fai/config/classes/50-host-classes" selects package classes to install. #! /bin/bash # assign classes hosts # use a list of classes for our demo machine case $HOSTNAME in faiserver) echo "FAIBASE DEMO FAISERVER" ;; demohost) echo "FAIBASE DHCPC DEMO" ;; gnomehost) echo "FAIBASE DHCPC DEMO XORG GNOME";; atom*) echo "FAIBASE DHCPC DEMO" ;; bear) echo "FAIBASE DHCPC LVM_XEN_SERVER XEN" ;; puma) echo "FAIBASE DHCPC RAID_XEN_VIRTUAL" ;; *) echo "FAIBASE DHCPC" ;; esac As the hostname remains unset during installation (and also after reboot) only a base system is installed. Guess this is problem has sth. to with debian squeeze or fai 3.4.2. Karl

Mika, explicitly speaking to you as you seem to be the one most up-to-date regarding live-initramfs and friends. At some earlier stage it was necessary to use HOSTNAME=gnomehost to make things work, then hostname=gnomehost used to work. Looking at the code in scripts/live in *lenny* there is explicit parsing of a hostname= parameter. This hostname parameter is *not* parsed in the version in squeeze anymore. Karl (or anybody else having a squeeze system at hand), could you maybe try whether using HOSTNAME=gnomehost makes things work? If this is the case, then we should definitely also fix this for squeeze (again speaking to Mika as FAI stable release manager :-) ). Best, Michael pgpAQGFCDo0Wt.pgp Description: PGP signature

Hi all, I've started to review these changes and added some fixes in 4.0~beta2+experimental22. However, there are still a few open issues from my point of view.

I believe this has since be fixed (LOGSERVER isn't even listed there by default anymore).

Re: Installing Debian Squeeze (i386) - No $HOSTNAME set
Hi, just updated to 3.4.3~rc1. All further observations refer to this version. 1. Use uppercase hostname/ip parameters in boot command line. Change to uppercase in "/srv/tftp/fai/pxelinux.cfg/*" or "/etc/fai/grub.cfg" APPEND boot=live FAI_FLAGS="verbose,createvt" FAI_ACTION=install IP=192.168.148.100:eth0:off HOSTNAME=gnomehost root=/dev/nfs nfsroot=192.168.148.11:/srv/fai/nfsroot I've added the HOSTNAME= changes, but I'm not that sure about the IP= stuff. I have also mailed Mika to seek further input from debian-live, if possible. I'll check it later. 3. ssh-command for fai-chboot (Calling task_chboot) requires user input. The authenticity of host 'faiserver (192.168.148.11)' can't be established. RSA key fingerprint is ... Are you sure you want to continue connection (yes/no)? Solution is to append the line "StrictHostKeyChecking no" to /etc/ssh/ssh_config (for nfsroot). No, fai-setup should be taking care of this, as good as it can. There should be some output resulting from echo "$sshdir/known_hosts created."; you might want to check the contents of that file. "$sshdir/known_hosts" is only created when FAI_LOGPROTO is "ssh". (I used LOGPROTO "ftp".) fai-setup:95> if [ "$FAI_LOGPROTO" = "ssh" ]; then 5.

Solution is to add a softlink: "ln -sf /proc/mounts /etc/mtab" I have no idea when df would be called, or which script should be calling it. It's called by "update-initramfs" (during fai-setup). Reproducible with: > r...@sque32:~# chroot /srv/fai/nfsroot/live/filesystem.dir > r...@sque32:/# update-initramfs -u > update-initramfs: Generating /boot/initrd.img-2.6.32-5-486 > df: Warning: cannot read table of mounted file systems: No such file or directory > warning: can't open /etc/mtab: No such file or directory 6.

No idea on this errors. Can't detect any problems caused by this. It's just installing the grub package in the NFSROOT, but it can (obviously) not be properly configured; should not pose any problems. grub-probe is called by grub-install, which is called by postinst of grub-pc (/var/lib/dpkg/info/grub-pc.postinst). IMHO it is not useful to call grub-install inside nfs-root during fai-setup. fai-cd (iso+usb) do their own grub install. Maybe it's better to install grub-pc unconfigured (dpkg --unpack).

Ok, I think I found the problem.
Karl, can you please do me a favour and try the following:
Edit /lib/live/config.sh and replace:
# 001-hostname
live-config.hostname=*|hostname=*)
LIVE_HOSTNAME="${_PARAMETER#*hostname=}"
;;
with:
# 001-hostname
live-config.hostname=*|hostname=*)
HOSTNAME="${_PARAMETER#*hostname=}"
export HOSTNAME
;;
and then rebuild the initrd (using update-initramfs).
Why it's working for you with HOSTNAME=.. in the kernel cmdline is
that the kernel's cmdline content is reachable and exported to
userspace and therefore the HOSTNAME you provide works within FAI.
Why it's not working with hostname=... on the other side is that the
argument to hostname=... was exported as $HOSTNAME in older
live-initramfs versions but the behaviour was changed starting with
live-config 2.0~a1-1 where it became $HOST, starting with git commit
a1486378484ab4aa86165fc0493be9ff57079725 (resulting in live-config
2.0~a4-1) it's the above mentioned $LIVE_HOSTNAME but FAI relies on
$HOSTNAME being set.
I pinged the debian-live people to make sure they are aware of this
regression for FAI, let's see if they can help us in coming up with
a solution working for both sides.
regards,
