Much to my immediate chagrin, removing write permission from a file does not seem to protect it from rm -f:
touch foo
chmod a-w foo
rm -f foo
How can I protect a file from accidental deletion when rm will be called with the -f flag? It looks like chattr +i foo would work, but it requires root on my system (is that intended?), so I'm looking for a non-root solution.
