On the SPARC platform, the following two boot options are new:
The -L option, which is used to print a list of all the available BEs on a system.
ok boot -L
The -L option is run from the ok prompt. This option only presents the list of available BEs on the system. To boot the system, use the- Z boot option.
The -Z option of the boot command enables you to specify a bootable dataset other than the default dataset that is specified by the bootfs pool property.
ok boot -Z dataset
The list of BEs that are displayed when you use the -L option on a device that has a ZFS boot loader reflect the menu.lst entries that are available on that particular system. Along with the list of available BEs, instructions for selecting a BE and using the -Z option to boot the system are also provided. The dataset specified by the bootfs value for the menu item is used for all subsequent files that are read by the booter, for example, the boot archive and various configuration files that are located in the /etc directory. This dataset is then mounted as the root file system.
