+# RAID, filesystems and encryption on both raw devices and partitions in all various combinations
 # need to be supported. Since full disk encryption is possible with GRUB as payload and probably desired/used
 # by most users, libreboot GRUB config tries to load the operating system (kernel) in the following way:
 
 	# 1. Try to decrypt raw devices first. This <your disk setup> inside a LUKS container is pretty common
-	#	a) Try LVM and RAID first, they might be used (accross multiple (raw) devices)
-	#	b) Always try LVM before RAID (LVM on (raw) RAID)
-	#	c) Try MBR/GPT partitions at last, one might still conviniently uses a single partition
