Hi Bruce, Yes, in the first and older Gentoo build I'm letting the kernel autodetect RAID1 to find /. That's the install that does NOT work mounting by label. In the second install I use an initramfs, / is on a RAID6 and is not autodetected. Rather I assemble the RAID6 within the initramfs using mdadm --assemble ####. The initramfs has both e2fsck & mdadm so it's able to assemble the RAID. It's also able to mount by label without any problems. Joost is suggesting that there might have been a thread earlier this year that said you must use an initramfs to mount by label, but I cannot find any grub documentation that supports that, and so far have not discovered the thread he's remembering. HTH, and thanks! Mark
