Just as a curious question, would a "kick" be functionally equivalent to
running the following 3 commands:

# svcadm clear <fmri>
# svcadm restart <fmri>
# svcadm enable <fmri>

I have nothing against implementing a "svcadm kick <fmri>", I just want
to check that I understand correctly what you mean. Indeed, at times I'd
use it myself, though I'm not sure whether it's good as part of the
upstream command set. I lack the data to call my experience
representative of most admin's styles.

Cheers,
