High folks... ...many machines, identical users on all of them, same subnet, possibly the same set of programs, etc. How come that, to me, this appears a prime entirely-diskless/NIS candidate? If so, check /usr/ports/net/etherboot, /etc/rc.diskless[12] and the handbook (http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/diskless.html, http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/nis.html). There also are an article on diskless (http://www.freebsd.org/doc/en_US.ISO8859-1/articles/diskless-x/article.html ) and some tricky examples in /usr/share/examples/diskless which took me a little while to get the drift of; mount_null(8) and mount_mfs(8) are your friends. Searching for 'diskless' on the web site also gives a lot of results (http://www.FreeBSD.org/cgi/search.cgi?words=diskless&max=250&source=www). Dunno wether this is any help to you. best regards, Peter. > -----Ursprüngliche Nachricht----- > Von: Danny Howard [mailto:dannyman@toldme.com] > Gesendet: Donnerstag, 28.
