We already do this for glibc in rawhide, for the symbol version under development. # Auto-generating dependencies for glibc development snapshots. # # A glibc development snapshot (say version 2.33.9000) may define # symbols in its under-development symbol version (GLIBC_2.34). RPM # automatically derives RPM dependencies such as # libc.so.6(GLIBC_2.34)(64bit) from that. While the GLIBC_2.34 # version is under development, these dependencies may be inaccurate # and could be satisfied by glibc RPM package versions that lack the # symbols because they were created from an earlier development # snapshot that had some other GLIBC_2.34 symbols. Therefore, if the # latest, under-development ELF symbol version is detected, this # dependency generator adds an explicit RPM dependencies on the glibc # packaging version against which an RPM package is built. <https://src.fedoraproject.org/rpms/glibc/blob/rawhide/f/glibc.req.in> This is an example build: util-linux-2.38.1-1.fc37 <https://koji.fedoraproject.org/koji/buildinfo?buildID=2042005> (util-linux-core in particular.) Right now, this isn't used much, but it when it is, it causes issues for developers who use the rawhide compose in chroots and newer builds leak into the chroot from the buildroot without a full chroot update. Manually ELN tagging can cause similar issues, so we no longer embed the dist tag in the auto-generated versions.
