To clone BEs, use the beadm create subcommand as follows:
$ beadm create BeFMRI
Ensure that the name you provide for the new BE is not an existing name. The new BE is created based on the currently active BE, but the new BE is inactive.
The command does not create partial BEs. The command either successfully creates a full BE, or fails.
The following options are available:
–a – Activate the new BE upon creation. By default, new BEs are not activated.
–d description – Provide a custom description to be used as the title in the x86 GRUB menu or the SPARC boot menu to describe the new BE. If this option is not used, BeFMRI is used for the title.
–e non-activeBeFMRI – Create a new BE from an existing but inactive BE. By default, clones are created from the active BE.
–e BeFMRI@snapshot – Create a BE from an existing BE snapshot.
–o property=value – Create datasets for a new BE with specific ZFS properties. Multiple -o options can be specified. See the zfs(8) man page for more information about the –o option.
