Same here: i have 50 machines running debian. /usr, /opt, /home are exported
via nfs (ro, ro, rw), and i'm useing nis for the password system. Working
fine, so far.
Installation: /home/install is a second mini debian, exported via nfs,
and mounted by a nfsroot bootdisk. it contains a script to do fdisking,
mke2fs, mkswap, and finaly untar /install.tar.gz (this is
/home/install/install.tar.gz).
since the machines are dual boot workstations with windows, i can't do direct
central system administration. that's why a wrote a script daemon (look
every 10 seconds for machines up with linux), and a maintaince script
(lots of rsync commands, useing ssh and a .shost).
the client/server differences are handled in the maintaince script
(long --exclude lists to not copy these files from the server,
and the sync the files from /root/pc to the machines).
the client-client differences are very small (xserver, scsi/ide, mouse),
and are only handled when installing: scsi/ide is detected via sfdisk,
xserver is detected via lspci, and mouse: try com1: and fix manual if it
fails (3 or 4 ps2 mouses total). the kernel is big and generic to support
all types of hardware.
