(Note that the first "partition" will +always be the partition map itself.) Then type + +<informalexample><screen> +$ hformat /dev/<replaceable>sda2</replaceable> +</screen></informalexample> + +Take care that you use the correct device name for your USB stick. The +<command>hformat</command> command is contained in the +<classname>hfsutils</classname> Debian package. + +</para><para> + +In order to start the kernel after booting from the USB stick, we will +put a boot loader on the stick. The <command>yaboot</command> boot +loader can be installed on an HFS filesystem and can be reconfigured by +just editing a text file. Any operating system which supports the HFS +file system can be used to make changes to the configuration of the boot +loader. + +</para><para> + +The normal <command>ybin</command> tool that comes with +<command>yaboot</command> does not yet understand USB storage devices, +so you will have to install <command>yaboot</command> by hand using the +<classname>hfsutils</classname> tools.

The partition +must not be otherwise mounted during this procedure.
