[w0m]

Personally; only issue i tend to have is that when I install X, it breaks Y forcing reinstallation of ~everything. What should be a small install ends up taking 30m of cleanup.

Entirely likely it's user error on my part; but also problem I haven't really had with other 'nix package managers.

Which isn't funny when Y is Postgres and your database is no longer readable post-upgrade. Happened to me.
