Without using a revision integer, `guix package --upgrade` will not work correctly, since Git hashes do not increase (or decrease) reliably. For example, the computer can't tell which of these two version strings is the newer version: "0.0.0-deadbeef" "0.0.0-cabba9e" Not all packages declare a revision variable, but I think it is helpful. Any suggestions on improving this part of the manual? It *does* explicity describe this problem and the solution. Should we add the revision variable to the code example?
