Comment(by dsd):

 /etc/fstab is not a definitive source of mount options or filesystem
 types. (I bet it says ext3 on XO-1 as well)

 On our kernels (and probably any recent regular distro), mounting as
 "ext2" and "ext3" and "ext4" is exactly the same thing - it goes to the
 same filesystem driver, there is no longer a separation. The difference is
 only defined at filesystem creation time (and we use mkfs.ext4).

 Is this causing you problems or is it more a cosmetic issue?
