 It's hard for us to ensure a valid /etc/fstab entry for / because at
 build-time, we don't know which fs will be used.

 Dracut tries to be clever and reads /etc/fstab before switching root, and
 notices that we've mounted with the wrong fs driver, so it attempts to
 "correct" the situation. This breaks non-versioned boot (the case where it
 can actually find fstab) e.g. tries to remount jffs2 as ext3

 Dracut can be asked not to be so clever with a boot time parameter, we
 need to extend this to be modifiable with a variable, that way we can
 disable it from an OLPC dracut module.
