Ambiguity is not ok.

That seems perfectly reasonable.

This was my first thought as well, though I think a separate keyword
would be nicer.

Yeah, that is a bit too non-standard.

I think my preferred solution would be to prefix all keywords with
"--". This would also allow you to use keywords in other actions
without weirdness ("rc.d start --stopped" would be nice, but "rc.d
start daemons sshd"/"rc.d start -- sshd" would be horrible).

I suggest the grammar to be something along the lines of:

$name list [--started|--stopped|--auto|--noauto|<daemon>...<daemon>]

(or whatever the syntax is for an arbitrary list of daemons).

Cheers,

Tom
