FWIW what I do is that I have some datasets in the GZ that I mount with lofs in
my smartos zones that contain the data I want to keep (each dataset belongs to
one zone only).
e.g.
/export/${UID}-pgsql
/export/${UID}-foo
"Updating" (re-creating really) the zone with the updated image is just a
matter of vmadm create foo.json and a run of whatever cfg management tool you
use (or even rsync/scp).
My json file contains things like:
"filesystems": [
{
"source": "/export/${UID}-foo",
"target": "/mydata",
"type": "lofs"
}
There're probably more|better ways to achieve what you want but but this one is
easy and works for my needs.
