Exactly, but in our case we don't want a separate partition for /usr (never
understood why anyone would since 1GB drives became affordable).  As a beadm
user I'm also assuming a rollback-able boot image would need to include /usr
in the root filesystem.

To do this in bsdinstall/scripts/zfsboot requires a 'mkdir' instead of 'zfs
create'.  Looks like it might be a matter of copying the $MKDIR_P around line
1125 but am testing that now.
