The main “instability” I’ve found with testing
or sid
is just that because new packages are added quickly, sometimes you’ll have dependency clashes.
Pretty much every time the package manager will take care of keeping things sane and not upgrading a package that will cause any incompatibility.
The main issue is if at some point you decide to install something that has conflicting dependencies with something you already have installed. Those are usually solvable with a little aptitude
-fu as long as there are versions available to sort things out neatly.
A better first step to newer packages is probably stable
with backports
though.
Ah NFS… It’s so good when it works! When it doesn’t though, figuring out why is like trying to navigate someone else’s house in pitch dark.
