For hysterical raisins, TLU uses update-tlmgr-latest.sh, rather
than executing tlmgr's self-update. I've never bothered to learn
exactly how update-tlmgr-latest.sh works, but I think runme.sh is
looking for xz in the moral equivalent of /tmp/installer/xz, but
whether it wants to execute it or copy it, I can't say. Does that
sound possible?
