can be recovered across subnets after booting either from a
bootable tape created by the Ignite-UX make_boot_tape
command or the system boots directly from the Ignite-UX server.
Booting directly from the Ignite-UX server can be automated with
the Ignite-UX bootsys command or interactively specified on
the boot console.
