efibootmgr seems to have release tarballs at e.g. https://github.com/rhboot/efibootmgr/releases/tag/18. Could we switch to them? Thanks!
The only difference between the "release tarballs" and the github-generated ones is an RPM spec file that we ignore anyway. The relevant target in the Makefile runs git archive, unpacks the resulting tarball, generates efibootmgr.spec, and then repacks the archive. https://github.com/rhboot/efibootmgr/blob/main/Makefile#L59 So yes, we could switch, but without really gaining anything by it.
