Good point - I didn't see that.
I agree with you, but my personal experience with the upgrade was quite
smooth in my
three home machines: 1 old laptop I use as server, 1 tower I use for NAS
and my personal
laptop which is a 4x4 multi purpose system - being my notebook a 1 and half
year old and
the other two 1 year old each.
All I had to do was remove a few packages that had files installed in
/lib, update glibc
reinstall them and continue with my life :)
The beauty behind this is we are now enjoying the new paradigm without
reinstalling the
system while with other distros your only chance to make the switch is
reinstall not only
your OS but everything else!
Cheers.
