Not only that, but I'd like to update my UID scheme from a pre-standard version (most of the UIDs are down in the 100s) to the new convention so that I'm more in-line with the rest of the world. My rough idea: 1) Create a "migrate" account in Wheel with home as /var/migrate so that I can do a dump/restore on "home" without messing things up 2) Start putting together all the pieces - trying to find update / conversion scripts whenever possible. 3) once things get close, do the dump/retore of home, and a tar/untar of /var/mail (since I'm moving it from a part of the /var filesystem to a filesystem of its own - doing a dump/restore on /var is not a practical migration strategy in any case) 4) Let people move in, try it out, see how things are 5) Fix everything found in #4 6) Try a cut-over and make sure all the network services work in the middle of the night sometime, then switch back 7) Nuke /home and /var/mail and migrate them again to get the latest version 8) Do the real switch 9) spend a couple of weeks fixing all the things that weren't so disastrous that they got picked up in #4. Ideas / scripts / project plans / outlines - whatever? Maybe I should write a chapter for The Complete FreeBSD after surviving this... -- John Lind john@starfire.MN.ORG
