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.
