Hmm ... I just noticted "sv start" which appears to combine "sv up"
and "svwaitup".
In situations where the initiator is willing to block and wait, perhaps
"sv start" is reasonable.
In other situations, the initiator does not want to block, but later on
some dependent wants to ensure that the service is up.
Is "sv start" also applicable in this situation ?
