`sv check' only exits non-zero if the following are both true:
The service is in the up state
A check script exists and exits non-zero.
Check is, I believe, intended to cover the ground between when runsv
considers the service up (in state run) and when the service has
completed initialization. This is important for things like databases
that might take a while to be ready.
To get the functionality you want the dependent service should, as
part of its runscript, do something like 'sv status $otherservice |
grep "run"' to see if runsv considers the service to be running
followed by a call to 'sv check $service' to see if the service is
available.
Cheers!
