This is occuring because the DHCP server isn't sending over ROOTSERVER, or you are configuring with a static IP so rootserver doesn't get set by the DHCP server.
Some of the networking bits must have changed in the debian kernel since the documentation was written. I got around this for USB/CD booting w/ network install, and also when NFS server is not the DHCP server by adding the following to the init script: /srv/fai/nfsroot/live/filesystem.dir/usr/share/initramfs-tools/scripts/live: · Here are the relative line numbers. We are adding a case statement, and then re-setting the ROOTSERVER variable after do_netsetup in the do_netmount() function. This also sets the SERVER variable for updating the tftp boot file. i. 52 SERVER=*) ii. 53 server="${ARGUMENT#SERVER=}" iii. 54 export server iv. 55 ;; v. 679 ROOTSERVER=$server recreate the initrd # chroot /srv/fai/nfsroot/live/filesystem.dir update-initramfs -k all -t -u And copy it to your USB, CD Image, or TFTP folder #cp /srv/fai/nfsroot/live/filesystem.dir/boot/initrd.img-VERSION /srv/tftp/fai/ Then add the 'SERVER=0.0.0.0' to your kernel append line, replacing 0.0.0.0 with your NFS server. Here are the only instances where the variable is used (so for boot=live or boot=nfs, but root=/dev/nfs will work for boot=live as well) scripts/live: NFSROOT=${ROOTSERVER}:${ROOTPATH} scripts/live: NFSROOT=${ROOTSERVER}:${NFSROOT} scripts/nfs: NFSROOT=${ROOTSERVER}:${ROOTPATH} scripts/nfs: NFSROOT=${ROOTSERVER}:${NFSROOT} On Thu, Jun 14, 2012 at 9:38 AM, Nicolas Courtel <cour...@cena.fr> wrote: > Le 12/06/2012 19:14, Steve B. a écrit : > >> I keep getting the error when the target boots; Trying netboot from >> :/srv/fai/nfsroot ..
