[OmniOS-discuss] unexpected BE snapshots

[Paul B. Henson]

I decided to go clean up some old boot environments, and noticed some
unexpected snapshots of my new 151010 BE. Before I cleaned up, it looked
like this:

rpool                                          2.56G  36.6G    37K /rpool

I noticed the new 151010 BE had a number of snapshots I didn't make; the
dates are particularly odd given 151010 wasn't released until May
something and I didn't install it until Junish.

After running beadm to delete my old BE's, it then looked like this:

rpool                                          2.02G  37.1G  36.5K /rpool

rpool/ROOT/omnios-r151010 at 2014-06-16-18:55:29   412M      -  1.01G  -

Five of the 151010 snapshots had disappeared, presumably cleaned up by
beadm? Are these beadm managed snapshots something new? I don't recall
ever seeing them before. Can I just delete them manually or would that
break something? Between the two of them that are left, they seem to
be sucking up about 1 gig or so.

Thanks...
