Hi yet again, (1) sda sdb confusion: Hadn't ever experienced sda and sdb changing assignments in my system -- except one period years ago when the pin contacts on my IDE/PATA caddies got a bit wonky. In my backing up system, I'm clear about the physical location of master and backup drives, and include a visual (LED-on) confirmation of drive assignment before the shell script starts the RSYNC command. First time using SATA. Hope it doesn't introduce any randomising factors. (2) LABEL a possible bullet-in-the-foot: As every single file and directory is copied in my backup system, it may COPY the master disk label on to the backup disk, creating a dual identity problem from then on. But if it does NOT copy the label across, then the backup disk would not boot (in a restore situation) due to an invalid identification problem, similar to the UUID that I'm working around. Thanks for thinking about it, though. Carl p.s. And =still= no one has actually commented on the adequacy and accuracy of the proposed editing in the boot-up configuration files in my original post. Sigh. On 22/04/14 13:03, Daniel Jitnah wrote:

Want to disable UUID, and address hardware directly by device and partition specs.
Hmm.
My knowledge is low. (Barely understand what I'm writing.)
Hmmmmm.
There benefits of UUIDs outweighs the disadvantages for the majority of users. Given your own admission of a lack of knowledge, what makes you sure you want to second guess what is a very sane default made by technically capable decision-makers?
You have every right to shoot yourself in the foot, so I won’t stop you, but I’m curious why you want to do so.
+1.
The biggest reason for this is decreased determinism in module loading order -- e.g. at least *in theory* it might load USB, then PATA, then SATA one boot, then next boot it loads SATA then USB then PATA.
A "*in theory*" that I experienced quite frequently not so long ago, not exactly in the sequence above, but /dev/sda and /dev/sdb frequently interchanged.
If UUID are hard to deal with, ie: readability, LABEL may be an alternative. If my memory is right, OpenSUSE uses Labels instead of UUIDs.
Daniel.
