151 default: /usr/{local/}lib/yaboot/yaboot same as

154 [ -C config_file ]

155 -m, --magicboot pathname to a OpenFirmware magicboot (CHRP) script

156 --filesystem set the filesystem type of the bootstrap partition

157 available options are hfs, msdos, and raw

158 [ --filesystem hfs ] default is hfs

159 --nobless don't bless the root directory, this should only

160 be used if you are using a MacOS boot partition

161 as the bootstrap partition (not recommended)

162 -M, --mount don't use userspace hfsutils to modify the

163 bootstrap instead try and mount the filesystem

164 directly. Note that attributes cannot be set

165 this way and you will have to manually modify

166 OpenFirmware to make your system bootable

167 --protect set the read-only (locked) bit on all bootstrap

168 files

169 --hide set the invisible bit on all bootstrap files

170 this is useful of you don't want them to be

171 visible from MacOS.

172 --nonvram do not update the boot-device variable in nvram.

173 --force don't ever ask for confirmation

174 -v, --verbose make $PRG more verbose

175 --debug print boring junk only useful for debugging

176 -h, --help display this help and exit
