  # managers, but doesn't do us any favors where we already had a system for
  # dealing with upgrades (and downgrades!). We'll change these libraries to
  # use the versioned naming system of glibc-2.33 and earlier so that we don't
  # have to handle these files differently and so that it's easy to see what
  # version of glibc is in use at a glance.
