Lists information about the existing boot environment, which is beName, or lists information for all boot environments if beName is not provided.
Note: Using beadm Utility (Tasks)
You can use the beadm utility to create and manage snapshots and clones of your boot environments.
Note the following distinctions relevant to boot environment administration:
* A snapshot is a read-only image of a dataset or boot environment at a given point in time. A snapshot is not bootable.
* A boot environment is a bootable Oracle Solaris environment, consisting of a root dataset and, optionally, other datasets mounted underneath it. Exactly one boot environment can be active at a time.
* A clone of a boot environment is created by copying another boot environment. A clone is bootable.
