You really want apt and deb based distros like ubuntu if you want to
go this route.
Are you saying that upgrading Centos is not advisable/reliable path and
Ubuntu is better in this area?
(pls, im not trying to start flame, pardon my ignorance :)
Debian and apt are very good at packaging. If you want to upgrade from
one distribution to a later version, they have done it well before yum
was in a position to achieve that. yum in FC5 should be able to
dist-upgrade to FC6 and so on...but I have not actually done it.
Personally, I never upgrade the OS. I simply install the fresh one,
but its
fine on my laptop, not for my clients.
Use images then if all your 400 workstations are identical.
Yes, previously I just clone the HD, but thats ok only for new install, not
preserving the data/user settings.
That is what partitioning or networked home directories do. Preserve
user data and settings.
I'm willing to go to every clients at first install if needed, but not
every year or so
for maintenance. I need setup and forget setup :-p
Well perhaps you can take a proper look at it then. I do not see why /
and /usr concerns your users at all. Using images to get what you want
out there in a flash is fire and forget. Of course, you need to do some
work on your staging box but when that is complete, you just toss your
new image to all 400 workstations and either wait for them to be
rebooted or have them reboot right away as you may choose.
