Everything works fine.
My question:
There are some zfs and some snapshots. Can I destroy them or are they
required?
Here is the list:
zfs:
zroot/ROOT/13.1-RELEASE-p9_2023-08-27_201128
zroot/ROOT/13.1-RELEASE_2023-08-27_195317
zroot/ROOT/13.2-RELEASE-p12_2024-08-24_192252
zroot/ROOT/13.2-RELEASE-p2_2023-08-27_223329
zroot/ROOT/13.2-RELEASE-p2_2024-08-24_185205
zroot/ROOT/14.1-RELEASE-p3_2024-08-24_192543
snapshots:
zroot/ROOT/default@2023-08-27-19:53:17-0
zroot/ROOT/default@2023-08-27-20:11:28-0
zroot/ROOT/default@2023-08-27-22:33:29-0
zroot/ROOT/default@2024-08-24-18:52:05-0

Once you're happy that everything is fine with 14.1 and you'll never
want to revert to a previous version, then you can delete the old boot
environments, and the snapshots they are based on. I generally run with
two boot environments -- the currrent one and one previous just in case,
but I haven't needed to revert to an older B.E. in a very long time.
Use `bectl destroy` to delete boot environments as this will delete
associated snapshots for you as well.
Cheers,
