There is also my 'rbk' (rebuild with KVM) tool in
https://github.com/bmwiedemann/reproducibleopensuse/
that uses 'osc build' underneath that works with our (openSUSE's)
open-build-service. It also works for other rpm-based (Fedora, Mageia, 
SLES and CentOS) packages in there.

I did not test it with src.rpms but the only significant difference is 
that the .changes file gets folded into the .spec file, which might make 
a difference for our process to set SOURCE_DATE_EPOCH.

The obs-build tool [1] will setup a build env from scratch for KVM and 
it also supports podman and chroot for isolation.
