-you to choose L for GNU/Linux,M for MacOS, or X for MacOSX before
-booting the default OS defined in defaultos=. If not set the value of
-timeout= (converted to seconds) will be used.
-
-usemount (same as -M or --mount)
-
-Whether or not to use the standard mount and umount utilities (and
-thus kernel space filesystem drivers instead of userspace utilities
-that manipulate the partition directly (through the device file). If
-this option is present ybin will insist that you be root. Note that
-using this option will prevent ybin from setting HFS attributes on the
-boot files (such as type and creator). This option is here mainly to
-allow ybin's use even if you do not have hfsutils. Default: no
-IMPORTANT: It is not possible to bless the filesystem when mounted
-this way, you will thus have to manually configure OF to make your
-system bootable.
-
-mntpoint=
-
-Requires `usemount' this works exactly like usemount does except it
-does not mount the bootstrap partition but rather installs the
-bootloader into the directory defined as the mountpoint. The pathname
-MUST be clean, ie no embedded spaces or metacharacters. The directory
-may not be more then one subdirectory deep from the root of the
-partition (not necessarily the unix /). You must not have a trailing
-/ either. This option is NOT recommended since it has the same
-limitations as usemount, your system will not be bootable by
-OpenFirmware, it will only be manually bootable or bootable if you
-change the boot-device variable to the direct pathname to the
-bootloader (which ybin will attempt to do).
-
-fstype= (same as --filesystem)
-
-This defines what kind of filesystem exists (or created by mkofboot)
-on the bootstrap partition. Possible options are hfs and msdos (if
-anyone can figure out how to get OF to execute a file on a ISO
-filesystem I will add that too) Note that if you use msdos filesystem
-you must have a DOS style partition table and not a Apple partition
-map. (it also requires that usemount be yes) yaboot may not yet
-support this configuration. The "raw" type causes ybin or mkofboot to
-copy the bootloader (value of install=) to the bootstrap without any
-filesystem. CAUTION: this will destroy any data or filesystem on the
-bootstrap partition (value of boot=) if you specify something like
-boot=/dev/sda you will destroy the partition table and lose ALL data
-on the disk. Default: hfs
-
-hfstype=
-
-This defines the 4 character code that should be given to the bootfile
-(the bootconf file will always be given type "conf") The main purpose
-of this is to make OF think its loading a MacOSROM image file and boot
-the system into GNU/Linux from the bootstrap partition as
-automatically as it would MacOS. In order for this to work you should
-set this to `tbxi' (the default in the included config file). If you
-have specified a OF wrapper (see above) then it will be given this
-filetype and the bootfile will be given type "boot" instead. NOTE:
-This appears to not work unless the bootfile has a CHRP boot script
-embedded in the header, at the moment yaboot lacks this script, see
-README.ofboot for more details. Default: tbxi
-
-hfscreator=
-
-This defines the 4 character creator code that should be given to both
-the bootfile and the bootconf files. This is largely pointless but if
-you use MacOS you could configure it so you have a pretty icon on the
-bootloader files. Default: UNIX
-
-nobless (same as --nobless)
-
-This prevents ybin from "blessing" the root directory of the bootstrap
-partition. This is Macspeak for "bootable directory" on the MacOS the
-System Folder is "blessed". Blessing the root directory will allow OF
-to find the bootstrap partition and load the bootloader automatically
-without reconfiguration (assuming the bootstrap partition is on the
-default disk (internal IDE in most cases). You should probably only
-set this if you are keeping the bootloader on a MacOS boot partition.
-
-protect (same as --protect)
-
-This defines whether the read-only bit should be set on the boot
-files, this is mostly pointless but slightly discourages
-tampering/deleting of the bootloader files if the bootstrap partition
-is mounted by MacOS. (hide below really would do a better job of
-that) This option will work with both msdos and hfs filesystems. It
-also works whether you have the usemount option set or not.
-
-hide (same as --hide)
-
-This defines whether or not the HFS invisible bit should be set on the
-boot files. This is a stronger way to make sure nobody fscks up your
-bootloader on the MacOS side of things. (A better option is a
-dedicated bootstrap partition with its partition type set to
-Apple_Bootstrap which is acceptable to OF but MacOS will refuse to mount
-it.) This option is ignored for msdos filesystems and will only work
-if usemount is not set.
-
-nonvram (same as --nonvram)
-
-This option prevents ybin from using nvsetenv to set the OpenFirmware
-boot-device variable in nvram. This is currently required for IBM
-machines. NOTE: you should not use this option when dual booting
-MacOS, it will cause the MacOS boot menu entries to fail on some
-machines.
