    I never experienced a filesystem failure since the advent of the
first journaling filesystem, Reiserfs. 20y ago or even more. Compared to
other accidents, this is therefore negligible. And, anyway, loosing one
partition, eg /var, would leave the package manager in a very dirty state.

    By "badly broken", I mean that, at either you can't boot it or fix
it up with some alternative boot method, or the package manager if so
f...ed up that you're unable to recover. The last happened a few times
to me.
