This will be fixed in future releases. Use persistent device naming
symlinks (i.e. /dev/disk/by-id/xxx) instead of openfirmware aliases for
boot, bsd, macos, macosx and darwin variables in Squeeze.

That is why we use persistent device naming symlinks (i.e.
/dev/disk/by-id/xxx) instead of traditional unix device names (i.e.
/dev/sdaX).


For example, this yaboot.conf was generated by d-i:

boot="/dev/disk/by-id/scsi-SATA_HDS728081PLA380_PFDB32E9SM6Y4M-part2"
device=/ht at 0,f2000000/pci at 7/k2-sata-root at c/k2-sata at 0/@0
partition=3
root="UUID=45780a5d-5764-47f5-bcd9-430c770d6ed7"
timeout=100
install=/usr/lib/yaboot/yaboot
magicboot=/usr/lib/yaboot/ofboot
enablecdboot
macosx="/dev/disk/by-id/scsi-SATA_WDC_WD1600JS-75_WD-WCANM1733293-part3"

image=/boot/vmlinux
	label=Linux
	read-only
	initrd=/boot/initrd.img
	append="video=TV-1:d"

image=/boot/vmlinux.old
	label=old
