Supported Scenarios

The goal of this document is to have a single source of information which scenarios are supported by yast2-bootloader.

bootloaders

grub2
grub2-efi
- only for UEFI boot
- only with GPT (see bug)
none

Partition table

DOS partition table
GPT
- requires bios_boot partition if stage1 will be on disk
DASD
- only s390x

storage configuration

software RAID
- /boot cannot be on RAID unless it is RAID1
- cannot have stage1 on MD RAID1 ( so no /boot on RAID1 )
LVM
- /boot cannot be encrypted (not bootloader limitation see bug)
multipath
Device mapper
local hard disk (including USB/ieee1394)
local (hardware) RAID array of any type
BIOS-RAID (handled via DM-RAID or MD RAID)
iSCSI server with persistent IP address / disk identification
NFSv3,v4 share on server with fixed IP address

Architectures

x86
x86_64
ppc64(le and be)
- only GRUB2
- there must be at least one PReP partition which size must not exceed 8MB (see fate)
s390x
- /boot/zipl must be on ext fs ( unless upgraded from working zipl configuration )
- only GRUB2

Stage1 locations

MBR of disk where is /boot
MBR of identical disks in MD RAID if it contains /boot fate
/boot
extended partition
- /boot has to be on a logical partition
