When you plug in another potential system disk, you now have two partitions with LABEL=rootfs, which I would find even more confusing. But then, I'm someone who believes in tying the label physically written on the disk (eg magic marker) with the partition LABELs on that disk. > If all your devices have GPT partition tables you could also use > partition labels instead, as they will survive a re-format of the file > system. Since their invention, I personally use PARTLABELs to tie together the LABELs and the partitions' intended use. They can be quite long, but for me, something like Toto-Home suffices, where toto is the disk and /home is the use. Again personally, I avoid using 16-byte UUIDs altogether, so any grub-mkconfig is followed by my postprocessing to convert them all to LABELs, thereby making grub.cfg comprehensible for humans. (Wouldn't GRUB_ENABLE_LABEL be nice.) The only UUIDs in my fstab are the FAT ones (which I set manually on USB/SD devices if I'm doing the formatting) and any NTFS ones I'm forced to use. And the only devices are /dev/sr0 and /dev/mmcblk0p1 as appropriate. Cheers, David.
