Wrong... naming... Use (see man tun2fs) 'label' and pick something quasi 
unique. My drive for amanda's use as virtual tapes is labeled rather 
unimaginatively as


Its worked flawlessly now for in excess of a decade and 3 drives on the 
end of that cable. And I can do such things as:

Its a terabyte drive, with north of 64,000 spinning hours on it now.
Using blkid's may be ok, but its too volatile if something is changed.

When one needs to swap in a new drive, and do it with a simple act of 
commenting out that line in you fstab so it will boot. Shutdown, change 
drives, configure the new one to the same name, re-enable that line in 
fstab and do a hot reboot. amanda will have a tummy ache but can deal 
with it, or hang the old drive on another cable and copy as much as you 
can to the new drive. I've not had to do that for several years, 7.4 
according to my ti-30xIIs so my 82 yo wet ram is fuzzy.  Point being is 
that it Just Works(TM) 

Over that time frame, differences in how udev works have had that drive 
at 3 different /dev sdb|c|d addresses which did not effect the function 
in the least. AIR, its plugged into the sata4 jack on the motherboard.
