thanks for all your tips!
i removed the /etc/hostname file on the nfsroot and got everything
working again!
i have no idea where the file /etc/hostname (and the "fai-live-host"
hostname) came from...
thanks again!

What does the nfsroot's `hostname` command report as the current hostname?
Is it the same as the content of HOSTNAME or is it the original/unmodified
host's name?
I just had a look at the relevant documentation / code for Debian.
$ man hostname
[...]
The host name is usually set once at system startup in
/etc/init.d/hostname.sh (normally by reading the contents of a file which
contains the
host name, e.g. /etc/hostname).
[...]
$ cat /etc/init.d/hostname.sh
[...]
do_start () {
[ -f /etc/hostname ]&& HOSTNAME="$(cat /etc/hostname)"
# Keep current name if /etc/hostname is missing.
[ -z "$HOSTNAME" ]&& HOSTNAME="$(hostname)"
# And set it to 'localhost' if no setting was found
[ -z "$HOSTNAME" ]&& HOSTNAME=localhost
[ "$VERBOSE" != no ]&& log_action_begin_msg "Setting hostname to
'$HOSTNAME'"
hostname "$HOSTNAME"
ES=$?
[ "$VERBOSE" != no ]&& log_action_end_msg $ES
exit $ES
}
[...]
So...
If there is a /etc/hostname the hostname will be set to its content.
If there is NO $HOSTNAME then the host's name will be set to whatever
`hostname` reports. (Most probably the value provided by DHCP.)
If HOSTNAME still does not contain anything, set it to 'localhost'.
undocumented/implicit cases:
If there is NO /etc/hostname AND $HOSTNAME contains something then the
host's name will be set to $HOSTNAME.
If there is a /etc/hostname AND $HOSTNAME contains something then
$HOSTNAME is ignored and /etc/hostname's content will be used.
[Maybe there's a modified /etc/init.d/hostname.sh / /etc/hostname in
Hiro's initrd, which sets the hostname to fai-live-host?]
