Re: [opensuse-factory] Shared library policy - multiple providers for a single API/ABI

You are correct in that it is not specified. One could say that we were still
experimenting with what works. One arm of that experiment was Mesa-libGL1.

openblas [...] three libraries [..] each one carries its own SONAME
(libopenblas_serial.so.0, libopenblas_pthreads.so.0, libopenblas_openmp.so.0).

Different SONAME => different package names. It's that simple.

Now, it is trivial to set the SONAME for all three implementations to
libopenblas.so.0, but unfortunately rpmlint insist on the package name to be
libopenblas0 in this case, with no possibility to have different package names
for the three variants.

The pattern is [vendor-][libblah1][-variant].rpm, stemming from the "other"
arm of the experiment that is libatomic1-gcc6, libblasc2-openmp.
