SUMMARY: Flash Archives and Zones

The short answer is, no, they are not compatible.

The longer answer is, it might maybe kinda work in some
circumstances if you build the flar with non-global zones
halted.

http://hub.opensolaris.org/bin/view/Community+Group+zones/flar_zones

I tried to be clever and script the process of building
a list of files for the flarcreate(1M) command to exclude
portions of running non-global zones that I didn't want
in the archive, but was not successful in even building
flars let alone testing whether they could be installed
to recreate the system.

If anyone ever figures this out or would like to details
of what I did (and did not) figure out, feel free to contact
me.
