That should work.
One question/minor issue:

abuild warns about chown in the post-install script.

But it would seem that there's no other sane way to make sure that
/var/lib/sword belongs to the "sword" group: to make it belong to
root:sword in the package, this group must exist when the package is
built and when it is extracted.
I presume pre-install could do the latter, but manipulating groups in
a build script is insanity.

If I can ignore that warning (assuming it belongs in abuild), I have a
script ready to go.

What's the preferred approach?

Thanks,
Isaac Dunham
