If you start breaking stuff by removing files without the knowledge
how things work, you should expect harsh treatment from this list.
What's next, sombody complaining he cannot login because he removed
the passwd file?
Without any irony: I'm sorry if I didn't make things clear enough! The
problem here is that you understood I'd be complaining, which I really
wasn't! I was just asking! And I still think I asked questions that are
somewhat "valid", though I must admit, not in "normal" situations.
My project is an embedded system which has certain requirements that do
not meet in a "normal" setup. So, yes, there may come up very special
requirements where I could even imagine that /etc/passwd must be removed
(not that I'm about to do that). I don't see why it shouldn't be valid
to ask which files a certain program relies upon.
Anyway: I got you.
