I didn't know that either thank you altair4.
That depends on who or what set the UUID and why:
I just keep learning from you guys
That's the whole point. Glad it's not wasted effort.
Just a FYI
, I don't like UUID
, only because I have so many partitions it gets annoying to have to keep checking those long numbers when setting up mount points on a new installation. I never liked labels either, until the kernel guys decided to lump all drives under sdx
, making all partitions sdxn
. With USB drives
in the mix, the drive numbers are subject to shifting
at any time, so UUID
was the fix
, rather than code different designations for each type of drive
, as we had before. It's one of those things that was not broken
, but they decided to fix it
anyway, and induced the problem as a direct result. We, having no say so at that level of development, must just live with it, and cope.
Given the choice
between UUID and labels, I choose labels
. I label the partitions with the name of the mount point directory, wherever possible, so it's real easy to see what goes where. My / partitions
are labeled with the name
of the OS
installed there, with variations, in case I have more than one installation of that OS. It makes things easy for me, because all I need to see is the label
, to know exactly
what's on that particular partition.
