Description Shawn Webb 2014-09-27 12:18:33 UTC 
The zroot/var dataset lives outside of the ZFS Boot Environment created by bsdinstall, making the package database shared across BEs that might have different packages installed. To fix, set the canmount ZFS property to no. Talked in person with Allan Jude regarding this bug.

URL: https://svnweb.freebsd.org/changeset/base/272274

Log:
  Change the /var dataset in the default ZFS layout to have the
  ZFS property canmount=off so that /var/db/pkg and other such directories
  are part of the / dataset, and only /var/mail, /var/log, and /var/crash
  are excluded from the ZFS boot environment (beadm).

Comment 2 Allan Jude freebsd_committer freebsd_triage 2014-09-28 21:47:40 UTC 
Thanks for noticing this.

We'll try to get it into 10.1, it is rather late, but it is a tiny diff.

  MFC r272274:
  Change the /var dataset in the default ZFS layout to have the
  ZFS property canmount=off, making /var/db/pkg part of the / dataset, so
  installed package files are consistent with the package database when
  using ZFS boot environments (beadm).
