Comment 11 for bug 1113821

Symlinks would work, but we'd have to make sure that:
 - We still ship the main file as a conffile so the user can edit it or remove it.
 - We don't create the symlink if the source file doesn't exist.
 - dnsmasq follows symlinks (likely but still worth checking)

So yeah, that should work. Might be a bit confusing for some users, but from what I can think of now, should cover all the cases we care about.
