I'm not sure why you'd have trouble with conflicting changes, if it's a
text file.  Just treat it like any other conflict, and make the user fix
it.  What's tricky about that? Or just run darcs revert on that file, and
lose the conflicting changes.  None of the proposed approaches that
involved placing this database in darcs itself have suggested an approach
that would allow user-friendly handling of conflicting permissions
changes.  Amazingly enough, putting code into darcs does not make that code
better, and implementing ideas in darcs does not make those ideas any
better either.
