Author: kevans Date: Sat Aug 11 01:02:27 2018 New Revision: 337596 URL: https://svnweb.freebsd.org/changeset/base/337596 Log: libbe(3)/bectl(8): Kill off the 'add' functionality for now The mostly-undocumented 'add' functionality, from initial read-through, is intended for construction of deep ("bdrewery style") boot environments. However, it's mostly broken at this point. `#if SOON` it out on both sides so that we're not exposing a broken API/feature. Work will resume on it in due time.
