ok, the context is to serve diskless machines with a shared readonly
root. Here, the only config data you can have is the hostname, which
you can easily map into a private config onto a writable mfs partition.
Maybe you are right with your suggestions but i have one doubt: when
you execute the line
mount -u -o rw /
in /etc/rc, you use the (readonly) /etc/fstab which might be invalid
for some or all hosts. Maybe i should try to setup the mfs /var and
fill it up with the per-machine data at the very beginning, right after
HOME=/; export HOME
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/sbin
export PATH
so that all the rest is consistent with a regular setup ?
