Unrelated, but rc.subr has quite a few instances of code like

    eval $somecmd

where most likely plain

    $somecmd

is intended.  I don't think another round of expansions inside the
value of somecmd is what is expected here (it seems to be a common
misconception that the command (the first word) is somehow magic).
