Yes, it is. I gather you earn your crust by teaching mathematics. I earn mine
by managing computer systems. I can't afford to not know what may be the
results of my actions. The operating systems with which I have most
experience of attempting upgrades are Solaris and Linux. With neither of
these operating systems have I ever had a completely smooth upgrade, and
certainly the prevailing wisdom among professional Solaris users is NOT to
use the upgrade mechanism but rather to do a clean install on test hardware,
and then to transition your applications, data etc.
Only when you're happy with the performance of your applications on test
hardware do you do the same thing on production hardware.
Of course if you're an amateur desktop user, you may be quite happy with the
convenience of a distribution install, and be prepared to put up with
possible problems - your choice. As it happens, I recently upgraded my
principal deskunder system and my notebook to SuSE 8.2 from SuSE 9.0. In both
cases I saw the exact same error - the first time logging in to KDE after the
upgrade did not succeed, resulting in a hanging desktop, but subsequent
logins were OK.
Sometime later, I wanted to watch TV on my TV card - kwintv crashed. I deleted
preferences files, reinstalled RPMs, did all manner of good things but to no
avail - kwintv repeatedly crashed. I'm now running on a fresh install of SuSE
9.0 on a different disk where kwintv works quite happily.
So distribution upgrades may work happily for you. My experience with them has
been that they are NOT reliable, andI think it would be most remiss of me to
attempt to use such an upgrade path on a customer's production system.
