There is (at least) one slight issue that doesn't have an official solution yet: manual pages. It might be a good idea to do # rm -rf /usr/share/man/* /usr/X11R6/man/* immediately before an upgrade. If you don't do that, man(1) might serve you stale manual pages afterwards that were removed from the sets, containing information that no longer applies. All the same, so far, we don't officially recommend it, and even i usually forget about it when doing upgrades. Should that be automated? Or are there risks of downsides or side effects? I'm not sure. Either way, it's hardly a very serious problem, it's merely slightly annoying. Yours, Ingo
