+    change network information
+  disk [-i] [-s<seconds>] <device>|<uuid> [mount options]
+    With -i make <device> a bootable file system then (with or
+    without -i) arrange for the next reboot to use that device.
+    The device must already be formatted as a file system, with
+    -i it must be completely empty, without it must contain an
+    apparently bootable file system. -s (for example -s5)
+    specifies a delay in seconds to wait at boot time before
+    mounting the device.
+  memstick [-i] <device>|<uuid> [mount options]
+    Behaves as disk however options appropriate to a flash memory
+    stick are automatically added
+  nfs [-i] <nfs mount path> [mount options]
+    <nfs mount path> must be a mountable NFS file system.  With
+    -i the partition must be empty and is initialised with a
+    bootable file system.  Without -i the partition must already
+    contain a bootable file system.  In either case the NFS
+    partition must be available to be mounted without root id
+    sqashing (i.e. root must be root) and it will be selected
+    as the root file system for subsequent reboots.
+    A default set of -o options are provided, additional options
+    may be given on the command line (multiple -o options will
+    be combined into a single -o).
+  flash
+    Revert to booting from the flash disk on next reboot.
+  ram
+    Boot (once) into a ramdisk, subsequent boots will be to
+    the flash file system.
+  preserve
+    Save the system configuration to the SysConf partition, you
+    will need to create the SysConf partition from the boot loader
+    before using this if SysConf does not already exist.  This
+    just runs 'sysconf save'.
+  restore
+    Restore a previously saved system configuration.  This just
+    runs 'sysconf restore'.
+ disk formatting:
+  The argument to 'nfs' or 'disk' must be an empty partition
+  of sufficient size to hold the root file system (at least
+  16MByte but more is recommended to allow package installation).
+  An appropriate ext3 partition can be made using the command:
+
+    mke2fs -j <device>  # for example: /dev/sda1
+
+  An appropriate NFS partition can be emptied using 'rm', but
+  must be set up (exported) on the NFS server." >&2
