Let's face it, thoose other names of the device is just symlinks, do a
find /dev/disk/ | xargs ls -ld and you will find only dirs. and
softlinks. But if the disk is mounted we are past that stage.
So that will only help you when the partition is to be mounted or when
you want to unmount it, after all, fstab and /dev/-names are just
for the user space. The kernel mostly only cares about the maj/min
numbers, or am I wrong?
What happens when you unplug your root fs, wait a few seconds till
the kernel gives up and then plug it in again ?
