I agree too. Actually, it makes more sense if we do a single package and
integrate there mechanisms to extract the needed files from xpis to
generate mozilla-locale-* packages instead of having each maintainer devise
its own (as well as redoing the registration of the packages in mozilla as
documented at [1])
Moreover, somebody (a packaging group) could just package the locale
definitions available for Mozilla [2], Firefox [3] and Thunderbird [3],
update them from time to time and update them whenever a new release is
produced. That would avoid all the bugs related to XXXX-locale-YYY
packages not allowing transitions of new Mozilla|Firefox|Thunderbird
versions because they have not been updated and having the binary package
proceed into testing would break them.
I believe that's actually how Mozilla is integrated in other OS, for
example, in Solaris IIRC.
