I really like this idea.

It still needs some thought on how to actually do that properly and what
to put into the tag?
 * URL to the distgit commit
 * buildsystem name + hash
 * different thing for each distro?

But it is fine to figure this out on the go. In the end I would like RPM
upstream to at least be able give some guide lines on how to use it.

We also probably need a way to set the tag via cli param or environment
variable so it can be set automatically by the build systems. This is
how this should be used IMHO.
