I've now put this into my /etc/rc.local:
------------------->
# Provide fresh random.seed for pxeboot
if cd /tftpboot/etc; then
rm -f random.seed
mkfifo random.seed
# do not fill up filesystem if the FIFO disappears
# dd of= does not block on open
sh -c 'while [ -p random.seed ]; do dd count=1 >random.seed; done' \
</dev/random 2>/dev/null &
fi
<-------------------
* It blocks until random.seed is read.
* It doesn't run amok if random.seed is accidentally removed.
* It's easy to identify with ps(1).
