My first instinct is to add a dependency on svc:/system/zones:default.
However, I think there is likely a race condition in that this
service will likely be online before the zones are actually fully up.
In particular, svc:/system/zones:default in the global zone may come
online prior to the appropriate routing related service in the
non-global zone.
Another approach would be to introduce a transient service that calls
a start script that does something like:
#! /bin/ksh
zone=...
svc=... # svc:/network/routing/route:default ?
function zonestate {
zoneadm -z "$1" list -p | awk -F: '{print $3}'
}
while [[ "$(zonestate $zone)" != running ]] ; do
echo "Waiting for $zone to start"
sleep 1
done
zlogin $zlone svcadm enable -t $svc
This new service could then list svc:/network/ntp:default as
"dependent" on this new service. An example of using "dependent" can
be seen in /var/svc/manifest/system/metainit.xml to cause
svc:/system/metainit:default to (e.g.) come up in single user mode.
