It's because you're using the wrong tool for this job ;)

Alternatives are used when more files can provide the same functionality
(e.g you can choose if the symlink /usr/bin/editor points to
/usr/bin/nano or /usr/bin/vim). The output of 'ls -l /etc/alternatives'
might be interesting for you.

By "locally diverting" Sven meant using dpkg-divert(8) which is the
correct tool for what he ended up doing.

Kind regards,
Andrei

I have a machine for which I want to manually manage grub.cfg and I
agree totally with you (and Sven, of course). It's a brilliant way of
doing it. Here is another Debian maintainer's view:

OK, thanks. The other link didn't make sense.
