174 not
175 provided, the new boot environment will be created as a clone of the

178 description is
179 also used as the title for the BE's entry in the boot menu. If the \fB-d\fR
180 option is not provided, \fIbeName\fR will be used as the title.

329 field indicates whether the boot environment is active now,

333 boot environment has a non-active parent BE, represented by 'x'; is active
334 on boot in a non-active parent BE, represented by 'b'. Activate, rollback
335 and snapshot operations for boot environments from non-active global parent
336 BE aren't supported, destroy is allowed if these boot environments aren't
337 active on boot.

339 Each line in the machine parsable output has the boot environment name as the
340 first field. The 'Space' field is displayed in bytes and the 'Created' field
341 is displayed in UTC format. The \fB-H\fR option used with no other options
342 gives
343 the boot environment's uuid in the second field. This field will be
344 blank if
345 the boot environment does not have a uuid. See the EXAMPLES section.
