I looked deeper into lib_package.bbclass and its history and I saw that
it wasn't updated very often during the last years. It still uses
hardcoded paths and doesn't include some files which would get packaged
without lib_package.bbclass.

What lib_package.bbclass does now, compared to the defaults from
bitbake.conf:

1.) It adds ${libdir}/*.a and /lib/*.a to FILES_${PN}-dev.

2.) It adds ${bindir}/*-config to FILES_${PN}-dev.

3.) It creates an additional package ${PN}-bin, which contains all other
executables: ${bindir}/* ${sbindir}/* /bin/* /sbin/*

4.) It doesn't package any of the following:
            ${datadir}/pixmaps ${datadir}/applications \
            ${datadir}/idl ${datadir}/omf ${datadir}/sounds \
            ${libdir}/bonobo/servers

In f624db1d3c7de3fcb3a9e76d388a8f9f8fedcf5c, Koen introduced
${PN}-static packages, but lib_package.bbclass has not been updated
since then, which was one year ago.

Although it packages ${bindir}/*-config into FILES_${PN}-dev, it does
not include the required mangling applied by binconfig.bbclass. I think
that's wrong and just causes unnecessary confusion. IMO, lib_package
should either inherit binconfig or not, but leave FILES_${PN}-dev
untouched in any case.

Leaving FILES_${PN}-dev untouched would also allow lib_package to
automatically inherit some updates from bitbake.conf and to create
non-empty ${PN}-static packages.

I don't know whether #4 should be changed or whether those directories
were left out on purpose.

So, my current proposal looks like this:

-
inherit binconfig	# ... or not

PACKAGES += "${PN}-bin"

FILES_${PN} = "${libexecdir}/* ${libdir}/lib*${SOLIBS} \
            ${sysconfdir} ${sharedstatedir} ${localstatedir} \
            ${base_libdir}/*${SOLIBS} \
            ${datadir}/${PN} ${libdir}/${PN}/*"

FILES_${PN}-bin = "${bindir}/* ${sbindir}/* \
                ${base_bindir}/* ${base_sbindir}/*"
-

Any opinions?
