Feedback:
It is very good to be able to go back to a former, working setup, but I expected something like a snapshot as VMware have.
But it seems that selecting default environment will boot into the latest configuration, i.e. including all the later changes.
I miss a way to go back to a certain point, before the settings got wrong ;-(
I read your explanation in a way that clicking on a white star should reestablish the config at that point in time, but it is not what I get.
Probably I misunderstand the terminology for "quick create", "Create/Clone" and "persistent".
I found it rather confusing, and a bit frustrating - after I had made some changes that invalidated DNS functions. I could not go back to the configuration from a few days ago!
The environments is a very new facility, but an explanation with some real examples to get back to a specific state would be very valuable.
Yours

That is expected, because ZFS Boot Environments do not include the configuration. The configuration history (console and GUI) and ACB already cover keeping older copies of the configuration to roll back that portion which is much less disruptive than rolling back the entire boot environment.
I'll add a note on that doc and link to the other backup/restore docs to make that more clear.

Actually I was wrong on that last comment. I ran some tests here and stepping back to a boot environment did revert the configuration as well in each attempt. The "cf" dataset with the configuration gets its own snapshot/clone as part of the BE process. It's possible that may not have been the case if you had an older ZFS layout on older versions of Plus, but it's not what happens on current code with a current ZFS dataset layout. It's also possible that changed between some point in the past and now. There may have been something else wrong on that system as well.
So the docs are OK as-is. I'll add a warning that BEs don't remove the need for good backups, though.
You may want to post on the forum for some insight into why your system behaved differently, though a fresh install of the newest release is probably a good idea as well.
