This is already possible via the `Postboot` functionality in Kayak, e.g.:

Postboot '/sbin/ipadm create-addr -T dhcp e1000g0/v4'

Just as with the old Solaris Jumpstart or AI, you can do this in
configs that are specific to a single machine (by MAC address) or
multiple machines (MAC prefix).  You can do pretty much any commands
here, and they get run by the once-at-first-boot service,
svc:/system/initial-boot [1][2]

One caveat is that this runs after the single-user milestone, so
pretty early in the boot, before networking and all filesystems are
available.  If you need to install additional packages, for instance,
you should look into some supplemental method of configuration
management.
