Why don't you start your FAI run remote? I have done some configuration
for my FAI setup and now I am able to install a computer remote.

During a fresh install I am copying the fai-kernelimage to
/tmp/target/boot/vmlinuz-fai. In /tmp/target/etc/lilo.conf I added a
special section for vmlinuz-fai called "reinstall". With the following
append line, the kernel uses the FAI nfsroot and starts a fresh install:
append="ip=dhcp devfs=nomount FAI_ACTION=install root=/dev/nfs nfsroot=123.456.789:/debian/fai/lib/nfsroot FAI_FLAGS=verbose,sshd,createvt,syslogd"

During installing a client it gets a normal kernel and the fai kernel plus
the append-line in /etc/lilo.conf.

During installation you can ssh to your installing client. If you want
todo a new fresh install, just edit /tmp/target/etc/lilo.conf to use
vmlinuz-fai to boot next time. Don't forget to run lilo!

If you want to test the result of your installation, just boot your
machine. Then you can ssh on it again (if network and ssh got configured
correctly) and test you fresh installed client. If you want to start a new
installation just edit /etc/lilo.conf again to boot vmlinuz-fai, run lilo
and reboot.

Works good here. With this trick I was able to migrate several Red Hat
Linux Servers to Debian Servers without leaving my chair... :)

Sincerly
