Well the UUID is supposed to automagically take on the proper
/dev/sda5 by itself if /dev/sda4 changes to /dev/sda5. I think
this is stupid and have felt this way from the first time I
started using Ubuntu. I was told it works fine and it really
is magic!
Well I have never encountered a situation that causes a
partition to change locations. I add a line in my boot file
that says for example, " # This is /dev/sda3". The UUID is a
jumble of characters you can not get /dev/sda3 from.
So the next step is to delete the UUID and replace it with
the simple actual data.
