Hi Renaud,
I like that as it does not break any thing else, but may catch some
people out in the future when zones autoboot that they were not
expecting based on the zone XML. And best of all it works now.
I was thinking of a RFE on how to add this feature. I came up with two
ideas and I would like to socialize them, to see what people think.
RFE: To be able to specify the boot order of a zone.
Method 1: (SMF mod only)
Modify the smf svc:/system/zones service to look for a file (say
/etc/zonesbootorder). If it is present it will boot the zones in the
order the appear in the file and the move on to boot any remaining zones
in any order.
Method2: (Enhance zones XML properties and rewrite SMF zones service)
Add an additional(optional) property to zones XML which contains a
numerical value for startorder (0-64K). The SMF service then starts the
zone by lowest startorder value first (1-64k). Two zones have the same
value means we don't care which one starts first. I would suggest we
also define 0 as "don't care"
Comments welcome.
The precedence of starting application in a multi tier environment has
always been a big issue and is normally solved by manual operator
intervention. This feature would alleviate that and be a compelling
reason to move to zones.
Regards
Rodney Lindner

I would not disable svc:/system/zones service because it can still be
used to start and stop zones that do not depend on other zones. On
the contrary, I would make the newly created services also dependent
on svc:/system/zones and make sure the zones that need to start in a
specific order have autoboot set to false.

Hi Paul,
The only way I can think of create your own services in the global
zone that will do a zoneadm -z zonename boot and have these service
depend on each other. You then have to disable the svc:/system/zones
service which is used to boot all zones during system boot.
Greetings,
Peter
