Mounting /home across different versions of K12LTSP presents its own set
of problems, I discovered this weekend. My primary server is running
3.1.2, and I just built a new server using 4.2.0. I mounted the /home
directory from the 3.1.2 box onto the 4.2.0 box, turned off DHCPD on the
old box, turned on DHCPD on the new box, and fired up a terminal. It
connected to the new server, booted, etc. The only problem was with
gnome. Apparently, something has changed as far as the settings in the
user's ~/ directory because I got errors and duplicate desktop icons and
the panels were messed up, had no menu button so no way to logoff, etc.
Not to say the problems are insurmountable, but I sure wouldn't call
it a transparent upgrade.
