The "shorter wins" makes sure we have a defined way. But for yum one even
better way of doing this might be to also check the comps file. If one
of the choices is mentioned there, then only use that one instead of the
above ranking.
This of course also means you'd have to mention sendmail in the comps/selection
file.
