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

160 install= in config file [ -i bootloader_file ]

161 -C, --config use alternate configuration file (ybin and yaboot)

162 [ -C config_file ]

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

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

165 available options are hfs, msdos, and raw

166 [ --filesystem hfs ] default is hfs

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

168 be used if you are using a MacOS boot partition

169 as the bootstrap partition (not recommended)

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

171 bootstrap instead try and mount the filesystem

172 directly. Note that attributes cannot be set

173 this way and you will have to manually modify

174 OpenFirmware to make your system bootable

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

176 files

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

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

179 visible from MacOS.

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

181 --force don't ever ask for confirmation

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

183 --debug print boring junk only useful for debugging

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