you are right, in FAI the kernel (or maybe the initrd) configures the
IP addresses and sets valid_lft and preferred_lft to forever.
Then a one-shot dhcp request is done, but with a different config and
dhcp script to write the file boot.log.
FAI does not start the dhclient to automatic renew the ip leases. This
is a bug.

As a workaround, you could write a hook, that starts dhclient.
Since the hooks are on the ISO and will be executed, this should work
until I release a new FAI version with a fix.
It would be nice if you could file a bug report for this.
