Okay, it looks like /dev/disk/by-uuid creates a symlink to which /dev/sdX location a given hard drive is mapped to. So if the /dev/sdX changes between boots, fstab won't care since the simlink will direct it to the new location. What I don't understand is how this is really all the different than using the UUID= method. Other than it's might be a little easier to remember to look in /dev/disk/by-uuid rather than udo /sbin/tune2fs -l /dev/hdX# | grep UUID, they both end up looking equally cryptic in fstab. -- John D.
