Does 'zoneadm -z halt' do a clean shutdown (run svc stop methods)?
Does init 0 in the global zone do a clean shutdown in non-global zones.

Interesting question. Zones are rebooted/halted VERY fast IMO. You can find out
this by writing hook in some /lib/svc/method/<script> stop routines like:

echo '$0 has been called' > /tmpfile

Let's try ... Hm ... no it doesn't. :-) (tried with
/lib/svc/method/smtp-sendmail, works if I do svcadm disable -t by hand)

No.
To do an init 0 in a zone from the global zone, run:
zlogin -S $zone /sbin/init 0

Yes, but if the zone doesn't shutdown within 60 seconds, it
halts it instead.

[This was in Solaris 10 3/05 -- I haven't checked if it changed since.]

Oracle is AFAIK supported in Solaris zones. This is interesting job oportunity
for an army of DBA's and backup opetators. :-)

Do you know if this is user-settable somewhere?  (Without modifying
anything that a patch would overwrite.)

No, it's in /lib/svc/method/svc-zones
It should really be picked up as an svc property. SMF wasn't
in Solaris at the time I wrote that part of what was the
init.d/zones script at the time, and whoever moved it under
SMF didn't do it either. You might even argue it should be a
per-zone property.

There's also a ceiling of 500 seconds in the system/zones.xml
manifest for the stop method.

Most SMF settings (if you make them directly svcprop) will be maintained
even if later patches apply.

60 seconds is the default timeout for a service, so that's probably
what's happening here.  Just change the default timeout for the zones
service to be what you want.

Looking at the current Solaris source, Dan seems to have done this now.
I don't know if that's appeared in a Solaris 10 update though.

....which has now been reduced to 100 seconds.
