Recently we made it possible to install a small number of locales by
supplying the rpm-macro “_install_langs”, for example
rpm -i -D _install_langs="en:de_DE" glibc-common.rpm
will install all English locales and all German locales which start
rpm -i -D _install_langs="en_US.utf8" glibc-common.rpm
will install only the en_US.utf8 locale,
rpm -i -D _install_langs="POSIX" glibc-common.rpm
will install nothing (but the POSIX/C is still available because it
is builtin into glibc).
Please note that this step in implementing the feature will break
deltarpms. Deltarpm requires the *full* data from the original rpm to
be installed in order to build the updated rpm from the deltarpm, so
the fact that we're only installing part of glibc-common will cause any
deltarpms for glibc-common to fail.
If I understand correctly though, the above is a stepping-stone to
subpackages containing the languages, which will *not* break deltarpms.
I do think the change is a great idea; I just want to make sure all
involved are aware of this potential pitfall along the way.
