Creating Custom Names for Boot Environments
A snapshot of a boot environment is not bootable. However, you can create a new boot environment from an existing snapshot. Then you can activate and boot that new boot environment.
$ beadm create -e BEname@snapshotdescription beName
Replace the variable, BEname@snapshotdescription, with the name of an existing snapshot. As described in the previous task, snapshot names use the format BEname@snapshotdescription, where BEname is the name of an existing boot environment, and snapshotdescription is a description of a specific snapshot made from the existing boot environment.
Replace the variable, BEname, with a custom name for your new boot environment.
See the following example.
$ beadm create -e BE1@now BE2
This command creates a new boot environment, named BE2, from the existing snapshot named BE1@now. You can active this boot environment by using the next procedure.
