Creating a new boot environment from the currently running boot environment remains the same as in previous releases with one exception. You can specify a destination disk slice for a shared file system within a non-global zone. This exception occurs under the following conditions:
If on the current boot environment the zonecfg add fs command was used to create a separate file system for a non-global zone
If this separate file system resides on a shared file system, such as /zone/root/export
To prevent this separate file system from being shared in the new boot environment, the lucreate command enables specifying a destination slice for a separate file system for a non-global zone. The argument to the -m option has a new optional field, zonename. This new field places the non-global zone's separate file system on a separate slice in the new boot environment. For more information about setting up a non-global zone with a separate file system, see zonecfg(1M).
By default, any file system other than the critical file systems (root (/), /usr, and /opt file systems) is shared between the current and new boot environments. Updating shared files in the active boot environment also updates data in the inactive boot environment. For example, the /export file system is a shared file system. If you use the -m option and the zonename option, the non-global zone's file system is copied to a separate slice and data is not shared. This option prevents non-global zone file systems that were created with the zonecfg add fs command from being shared between the boot environments.
