I ran into a "make srpm" issue in the buildsys (again, seen them before every
now and then) because I was using a feature in the specfile that is not
supported by the version of rpmbuild that gets run with "make srpm" there.
I suppose there are a lot of contributors that are not aware of this, so it
(along with some details exactly what to expect to (not?) work, maybe from
someone from the infrastructure team who knows the details) could be a worthy
addition to somewhere in the package maintainers documentation section in
Wiki. Main packaging guidelines?
