+ 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
