13 I don't even need that detail in my command line. (This box has five RAID-1
14 partitions, composed of identical partitions on identical SATA disks.) Mine
15 just looks like this:
16
17 kernel /boot/kernel-x86_64-2.6.27-gentoo root=/dev/md0 vga=0x31A
18 video=vesafb:mtrr:3,ywrap fbcon=scrollback:128k splash=silent

20 The md code in the kernel manages to find all the partitions at boot time
21 and stitches them together properly. No problem.
