This documentation is for yast2-bootloader and applies to SLE11 and openSUSE 11.0+. For older versions, use the documentation that comes with your distribution in /usr/share/doc/packages/autoyast2/
General scope of AutoYaST profile only bootloader part.
<bootloader>
<device_map config:type="list">

</device_map>
<global>
- info about configuration of installation (installation settings for GRUB and generic boot code)
</global>

</sections>
</bootloader>
You can define devices and their order in device.map, but it is not necessary. yast2-bootloader checks the devices during installation and proposes a device.map. It can happen that the order of the devices is wrong or you have defined a different order than the one set in the BIOS. Take care when you make changes there. The system might not boot afterwards.
<device_map config:type="list">
<device_map_entry>
<firmware>hd0</firmware> <!-- order of devices in target map -->
<linux>/dev/disk/by-id/ata-ST3500418AS_6VM23FX0</linux> <!-- name of device (disk) -->
</device_map_entry>
</device_map>This is an important if optional part. Define here where to install GRUB and how the boot process will work. Again, yast2-bootloader proposes a configuration if you don't define one. Usually the AutoYaST profile includes only this part and all other parts are added automatically during installation by yast2-bootloader. Unless you have some special requirements, don't specify the bootloader config in the XML file.

Attribute |
Values |
Description |
|---|---|---|
|
activate |
Set the boot flag on the boot partition. The boot partition can be "/" if there is no separate /boot partition. If the boot partition is on a logical partition, the boot flag is set to the extended partition. <activate>true</activate> | |
|
default |
Name (title) of the default boot section from <default>openSUSE 11.2 - 2.6.31.5-0.1</default> | |
|
gfxmenu |
Path to the graphical boot menu (/boot/message). Set to 'none' if you do not want to use a graphical boot menu. <gfxmenu>(hd0,1)/boot/message</gfxmenu> | |
|
timeout |
The timeout in seconds for automatically booting the default boot section from <timeout config:type="integer">10</timeout> | |
|
generic_mbr |
Write generic boot code to MBR, will be ignored if boot_mbr is set to "true". <generic_mbr>false</generic_mbr> | |
|
boot_mbr |
Write GRUB to MBR of the first disk in the order (device.map includes order of disks). <boot_mbr>false</boot_mbr> | |
|
boot_boot |
Write GRUB to separate /boot partition. If no separate /boot partition exists, GRUB will be written to "/". <boot_boot>false</boot_boot> | |
|
boot_root |
Write GRUB to "/" partition. <boot_root>false</boot_root> | |
|
boot_extended |
Write GRUB to the extended partition (important if you want to use a generic boot code and the "boot" partition is logical). NOTE: if the boot partition is logical, it should use boot_mbr (write GRUB to MBR) instead of generic_mbr. <boot_extended>false</boot_extended> | |
|
boot_custom |
Write GRUB to custom device. <boot_custom>/dev/sda3</boot_custom> | |
|
trusted_grub |
Use trusted GRUB instead of the classical GRUB (gfxmenu is deleted automatically if this option is true). Do not use trusted GRUB if your hardware does not support it. <trusted_grub>false</trusted_grub> | |
|
lines_cache_id |
Internal option specifying the cache id for perl-Bootloader. Do not use or change it in a cloned XML file. |
A list of initrd modules. Do not create your own list if you do not fully understand the impact. AutoYaST will take care of it for you.
Define which boot loader to use: grub, lilo, ppc or elilo.
<loader_type>grub</loader_type>
The configuration of the boot sections in the menu.lst is added automatically here by yast2-bootloader during installation. yast2-bootloader deletes boot sections with no valid kernel and initrd path.
