Ah!  Thank you!

I'll have to try this again, next time.

I really appreciate it.

Ok.  Now I'm real confused.  Assuming I had done something like this:

zfs snapshot rpool/zones/tomcat/ROOT/zbe at whatever

Done my work.

In the meantime, other auto snapshots were created...

This would not have worked:

zfs rollback -r rpool/zones/tomcat/ROOT/zbe at whatever

?

What would I have had to do to correct this?  Roll back each snapshot successively?  That could be kind of unpleasant if a lot of time had passed and a person needed to rollback through a lot of snapshots.

Or do I misunderstand that?
