Splitting every single lib in a separate package isn't ideal, IMHO
(just look at how many kde library packages we have).
Libraries that have the same major from the same src.rpm should be in
the same sub-package as much as possible (i.e. all glib-related libs
in one package, extensions (e.g. nautilus extensions) could be each in
a sub-package); and split only if something would require one lib but
not another from that lib package, i.e. split when needed, not
generally.
For example look at Amarok:
$ urpmf --sourcerpm :amarok | sort | grep lib
lib64amarokcore1:amarok-2.4.1-0.mga1.src.rpm
lib64amaroklib1:amarok-2.4.1-0.mga1.src.rpm
lib64amarokocsclient4:amarok-2.4.1-0.mga1.src.rpm
lib64amarokpud1:amarok-2.4.1-0.mga1.src.rpm
lib64amarok-sqlcollection1:amarok-2.4.1-0.mga1.src.rpm
lib64amarok-transcoding1:amarok-2.4.1-0.mga1.src.rpm
every lib is in a separate package, even though:
- Nothing else uses any of those libs other than Amarok
- Amarok is linked against all of those libs and it wouldn't work if
you uninstall any of them
In such a case grouping all of them in one lib*amarok package would be
easier, there'll never be any file conflicts when the mojor of any of
them changes.
P.S. I am not a packaging expert.
