beadm is mounting canmount=no filesystems

[dlangille]

On FreeBSD 9.3 release

$ beadm --version
beadm 1.0 2013/10/13

I have this:

# zfs get canmount system/bootenv/default/usr \
                   system/bootenv/10.1-RELEASE/usr
NAME                             PROPERTY  VALUE     SOURCE
system/bootenv/10.1-RELEASE/usr  canmount  off       local
system/bootenv/default/usr       canmount  off       local

After mounting:

# beadm m': beadm mount 10.1-RELEASE /mnt
Mounted successfully on '/mnt'

I notice /mnt/usr does not contain expected contents. Investigation shows a canmount=no filesystem has been mounted:

$ zfs mount | grep system/bootenv/10.1-RELEASE
system/bootenv/10.1-RELEASE     /mnt
system/bootenv/10.1-RELEASE/tmp  /mnt/tmp
system/bootenv/10.1-RELEASE/usr  /mnt/usr
system/bootenv/10.1-RELEASE/usr/local  /mnt/usr/local
