Somehow that sounds like a really bad idea to me. Admittedly manually
placing some file in /usr/include/libfm is pretty ugly, but I would
still certainly not expect that upgrading the libfm package would remove
it.

Is that really good practice? Can packages "own" a directory, so that
anything that the local admin puts there may be removed automatically?

Best,

-Nikolaus

Probably I'm wrong in that. Do you think preinst script should fail
instead if target-to-replace directory is not empty?

And that will not work certainly. If package is being upgraded then old
files will be still in place so rmdir will fail in any case.

Could you propose any better way to do then? Postinst script which does
rmdir and makes symlink instead of not-installed from package? Isn't it
dirty somehow?

Andriy.

Do not mess with /usr, that is exclusively the domain of dpkg. Any
file you place there may well be overridden. Use dpkg-divert if you
have to.
