we also have 'guix refresh --list-updaters' and 'guix lint
--list-checkers'.

'guix system', for file-system-type, shows '(one of 'ext4', 'iso9660')'
right in the options.

also 'guix hash' allows other formats but doesn't have a list-updaters

having "(one of 'tarball', 'squashfs', 'docker')" would be easier, but
IMO my patch gives more information, specifically about squashfs and
needing to run 'docker load'.
