This is not at all true. we have a minimal buildroot that is installed for every single build, the buildroot packages are the same across all builds. there is no BuildRequires pulled in until the buildArch task > Two shortcuts seem possible: > > (1) Limit the use of macros in Source lines, so that only a simple, > standard, perhaps pre-cached buildroot can be used. > > (2) Perhaps uglier: Just build an SRPM that contains everything in > dist-git + everything in the lookaside cache, and hope for the > best ...
