They aren't.  I think I should have changed the subject line.
(I've done that now.)  And probably switched to another mail list.
(SMF? I hesitated because I hate cross-posting.)

I wasn't just talking about boot order.  That probably wasn't clear.
That's just one of the many problems that could be solved by what I
suggested.  And that was SMF across machines, which is what a cluster
or a Service Oriented Architecture is about, and which is what we
almost have with SMF.  A real thing instead of all this marketing buzz
around SOA.

I mean this:

    <dependency name='my-great-database' type='service'
        grouping='require_all' restart_on='none'>
      <service_fmri value='svc://dbhost/application/postgresql' />

Wouldn't that be nice?

Do you see that attribute "restart_on"?
No, I won't ask the question that you mentioned up where I added the
[***] comment.  I already know how to to that with SMF.

So, should we move this to the SMF list?  Or forget it?
(As I said, there are most likely people who have thought about this.)
