sysidcfg in solaris 10 shared-ip zones

If you've tried to put a sysidcfg in shared-ip zones with multiple network interfaces, you've probably experienced some headaches.

I found that if I specified each interface like you would in a normal sysidcfg, it would drop to interactive input.

When I was just specifying one interface with network_interface=PRIMARY{etc etc}, everything worked fine. When I would switch to network_interface=e1000g0{primary hostname=server.local} , it would drop to interactive again.

The secret was just to use PRIMARY no matter how many interfaces I was configuring.

After some tinkering I was able to drop the whole network_interface{} stanza down to:

network_interface=PRIMARY{hostname=hostname.local}
