Actually, with minimal work in the rc.diskless* files, we have a very workable, large-scale system with / as Read-Only. In fact, only /dev and /var are read-write (well, in testing we also have a /sewer for coredumps) /dev and /var are local RAM disks (and /tmp points are /var/tmp) One of these days I will want to write up some of what we did. It really is rather nice to have a whole cluster of machines sharing the same install and the boot server. -- Michael Sinz ---- Worldgate Communications ---- msinz@wgate.com A master's secrets are only as good as the master's ability to explain them to others.
