A snapshot of a boot environment is not bootable. However, you can clone a new boot environment from an existing snapshot. Then you can activate and boot that new boot environment.
For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .
