Re: booting FAI kernel with initrd
[...] On a machine running a stock Debian kernel 2.6.18 (with etch) edit /etc/initramfs-tools/initramfs.conf and change to these lines MODULES=netboot BOOT=nfs I doubt that you really need these, actually I did not change my initramfs.conf and it still works. then mkinitamfs -o fai-initrd. This creates the initrd for net booting. Copy the the kernel /boot/vmlinuz-2.6.18-3-686 and fai-initrd to /srv/fai/tftp In pxelinux.cfg/ use this file: If you don't change initramfs.conf, you don't even need to run mkinitramfs ... - just copied over the kernel and the initrd that was already there. label fai-generated kernel vmlinuz-2.6.18-3.686 append initrd=fai-initrd ip=dhcp FAI_CONFIG_SRC=nfs://kueppers/usr/local/share/cs-etch FAI_ACTION=install root=/dev/nfs nfsroot=134.95.9.149:/usr/lib/fai/nfsroot-etch,v2,tcp,rsize=32768,wsize=32768 FAI_FLAGS=verbose,sshd,createvt For the sake of completeness, I'm using the following pxelinux.cfg/default: label fai-generated kernel vmlinuz-2.6.17-2-486 append ip=dhcp devfs=nomount FAI_ACTION=install root=/dev/nfs FAI_FLAGS=verbose,sshd,createvt,syslogd initrd=initrd.img-2.6.17-2-486 nfsroot=192.168.248.29:/srv/fai/nfsroot Actually one shouldn't need the additional nfsroot=..., if it is already provided by DHCP; however some versions of initramfs-tools seem to be buggy (and I don't know whether it got fixed already) and fail to parse the DHCP results.

Right, that seems to work. The root=/dev/nfs seems most important.

Right, I fail to get an installation started when not having nfsroot set on kernelk command line. So my orginal question, if/how this can be done with getting the nfsroot location via dhcp seems not yet solved In most situations it's enough to set it on the kernel command line, but it's not 100% compatible to the strategy of putting these features in the Kernel.

I think the initramfs-tools bug related to these problems is http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=387808 - and it isn't fixed yet... I guess it's just some small bug in the scripts running in the busybox, but I haven't found the time to debug it. Best, Michael pgpoXoDZuZ67c.pgp Description: PGP signature
booting FAI kernel with initrd
I like to answer this question from IRC lazyb0y did anybody ever create an initrd for fai that includes features to get the location of the nfsroot by dhcp and mount the nfsroot lazyb0y as opposed to having the kernel features compiled in and do that on the kernel level? h01ger yes,lots of peoole No, not lots of people. I think only oz, h0lger and I did this for FAI. It works this way: On a machine running a stock Debian kernel 2.6.18 (with etch) edit /etc/initramfs-tools/initramfs.conf and change to these lines MODULES=netboot BOOT=nfs then mkinitamfs -o fai-initrd. This creates the initrd for net booting. Copy the the kernel /boot/vmlinuz-2.6.18-3-686 and fai-initrd to /srv/fai/tftp In pxelinux.cfg/ use this file: label fai-generated kernel vmlinuz-2.6.18-3.686 append initrd=fai-initrd ip=dhcp FAI_CONFIG_SRC=nfs://kueppers/usr/local/share/cs-etch FAI_ACTION=install root=/dev/nfs nfsroot=134.95.9.149:/usr/lib/fai/nfsroot-etch,v2,tcp,rsize=32768,wsize=32768 FAI_FLAGS=verbose,sshd,createvt This boots my Thinkpad T60 without problems where the default FAI kernel does not work. Do not forget to change the initramfs.conf back to is previous version, otherwise the next kernel update will create an initrd which will not boot your machine any more (this happend to me once) or use the option -d. -- regards Thomas
