What i was originally thinking was to put /usr/src, /usr/obj, & /usr/ports on seperate filesystems but I didn't know how big to make them, but your way souund better and /usr/home was going to be seperate and NFS mounted from the fileserver anyway. All platforms are either FreeBSD or Windows, there is a Linux Firewall but thats getting replaced by FreeBSD as soon as I can get my head around ipfilter properly. The main idea was to allow say the fileserver to do the buildworld as you said and then the other systems to just do the installworld. I assume that in your setup that /ports/distfiles would also be a link to /share/distfiles, as not every system will contain the same ports as the other systems, or would the fileserver have to do 'make package' first on ports that were to be installed on other systems. So being that I have one 20Gb disk and two 40Gb disks what sort of filesystem layout would you reccomend? They are all IDE and I could just about stretch to another 40Gb disk at a push. Any help will definitely be appreciated, as this seems to be getting more complicated by the minute. Yes I definitely agree that this need documenting, setting up a fileserver to do src, ports, home dir's is a pain. Perhaps I'll consider writing somethig once I get this thing sorted.
