What is the mechanism to keep the uid-gid.txt aligned with tree content? is
there a CI check that says I am using the new acct-* eclasses AND I have a
UID / GID assigned that is not matching uid-gid.txt? I see the CI has
"ConflictingAccountIdentifiers", is this already doing this work (checking
that the ebuild matchines uid-gid.txt), or just scanning the whole tree and
ensuring that 2 packages don't re-use the same ID?
