Well yes. But that means that each user should be able to update, not
just the administrator.

In that case the file should not be packaged at all and it should live
in /usr/var somewplace, I think. But if you think a bit further you'll
see that this wouldn't be sufficient when the user cannot write there.

Again, if you package that updater, it'd make sense to create a
sub-package just for that and provide any customization as to which
update style is preferred (the things you mentioned are all sensible in
some situation, just not together). The longer I think about it the
less convincing the idea that a postinstalll script should do the actual
updating, although it might be one of the options you offer.

Achim.
