Hi Domen,
I just tried, it seems to do the trick. An example source setup that was
breaking the RPM building before, is now functioning seemingly correctly. The
produced RPM gets the symlink, pointing at the location outside of the package.
I would actually prefer if the code printed a warning in this case. (Requesting
a relocatable package, yet pointing at a fixed location outside of the
package.) As in our case it was definitely a mistake to include soft links like
this in our build. But if that's hard to add to the code, then so be it.
Cheers,
Attila
