Well, I'm not really seeking stability. All I want is not being afraid to reboot my server, and do it the more soldomly possible (so typically, not-so-frequent kernel updates).

The packaging under debian can be kinda boring sometimes (I need some personnal software that I will package myself), even if not that hard. thanks for your help though.
Another point that pisses me off under debian, is how exploded the libraries are. I compile softwares pretty often, and when I notice that a software need abc/foobar.h, I want to just install libabc, not libabc-foobar, libabc-foobar-dev, libabc-baz, libabc-baz-devel-blah, ...
