It sounds like simply copying in whole or part the relevant files from
the global zone and making the appropriate modifications to
$zonepath/root/etc/.sysid* (forget the exact file name) would be a
workable approach. This would have to be done from the global zone.

To the best of my knowledge, such an API is not even available to
query in the same zone (e.g. global zone querying global zone). Such
an API that allowed cross-zone queries of this information would cross
isolation boundaries that have been held rather dear with zones.

This approach, much like the one used by sysidconfig, is broken. What
happens when you use LDAP for everything except hosts and DNS for
hosts? If you are coming up with a new solution for setting up naming
services, please don't repeat this mistake.
You may want to take a look at zonemgr. It will do quite a bit of
customization of a zone without interaction and may be just what you
are looking for.
