How about making etc/random.seed a named pipe and feeding chunks
of /dev/random to it?
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).
Very nice. It seems like this might be a good addition to /etc/rc
because the OS depends on it. It's not like it's system, site, or
application specific.
The OS itself does not depend on it. This is only for machines running
an tftpd server, in order to feed random to kernels booted over tftp.
