I was looking into having a service get notifications when an optional
dependent service came online or offline. There doesn't seem to be a
1-step way of getting this. If I set restart_on to refresh I will get
notifications if the service is stopped, but my service won't be restarted
if the dependent service is started.
So, service foo has declared
<dependency
name='foo'
type='service'
grouping='optional_all'
restart_on='refresh'>
<service_fmri value='svc:/bar' />
</dependency>
If bar is disabled, and foo is started, foo will not be notified if bar
comes online later. question 1, is this correct?
I also noticed I can work around this by creating a pseudoservice baz, and
declaring baz to be exclude_all on bar, and foo to be optional_all on both
bar and baz. Question 2, am I correct in my understanding here?
Are there any plans for more detailed notifications for service
transitions for dependencies that might help with this?
