Yes I imagined that detecting /var/lib/rpm was one way to deal with
the problem (but not /etc/*-release as this is exactly what I want to
avoid: having to map distributions to packaging system).
I was hoping that there was some magic command a la lsb_release which
could have helped for this). Well I guess I'll have to rely on some
heuristic like those for now.
Would there be a possibility (for the long term) to add such a
facility. I understand that this is quite difficult as it requires
some synchronisation between distributions.
For the record, I'm just trying to have my cmake based build system to
decide which packaging scheme it should use on a given linux machine...
Thank's for the answers.
Theo.
