Solved A new ZFS boot environment management library and tool

Interesting... to my eye beadm looks to already be BSD-licensed. (Indeed, pkg info beadm reports BSD2CLAUSE, so not just to my eye, then.)

Regardless, it will be interesting to see where this goes.
Briefly (without me trawling logs of IRC, and so on): if I recall correctly, the motivations for this novelty were primarily technical; not license-oriented.
