            Bug ID: 253445
           Summary: bectl: does not function in two-level zfs datasets
           Product: Base System
           Version: 12.2-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: bugs at FreeBSD.org
          Reporter: dougs at dawnsign.com

I used mfsbsd to set up default datasets. If using non-raid, by default, mfsbsd
formats its zfs datasets for a single disk as follows:

Filesystem 1K-blocks Used Avail Capacity Mounted on
tank/root 302305222 9711156 292594065 3% /
devfs 1 1 0 100% /dev
tank/root/tmp 292594102 37 292594065 0% /tmp
tank/root/var 292924432 330366 292594065 0% /var

When I attempt to list bootable environments, it comes back empty.

[root at squid 11.Feb 12:20pm /usr]# bectl list
[root at squid 11.Feb 12:20pm /usr]#

bectl check does not return anything:

[root at squid 11.Feb 12:20pm /usr]# bectl check
[root at squid 11.Feb 12:20pm /usr]#

I would like to implement boot environments using two level datasets.

Is the three level datasets a requirement for using bectl?

for additional details.
