What do you mean by "really internal"?
It is needed to make protoc-C happy and compile opts.proto and everything
that uses it. We don't actually use it inside criu, but we use it in 
crit, where everything
is being compiled properly with protoc, which is a bit smarter than 
protoc-c, but still
requires descriptor.proto from protobuf-devel.

But, i think, descriptor.proto is quite standalone and could be just 
copied to
protobuf/google/protobuf. But do we really need to copy it?
Is having  an additional protobuf-devel package really problematic?
