As other readers have noted, using UUID's for the fstab first field
(fs_spec) is okay. Newer Linux kernels offer more meaningful options,
such as GPT labels and drive make/ model/ serial number (ID) strings.
AFAIK, these options have nothing to do with the kernel. They are
provided by libblkid. The only related option added to "newer" (it was
3.x so not really new) kernels is the ability to specifiy the root
filesystem by PARTUUID instead of device node name or major:minor
numbers when not using an initrd or initramfs to mount the root filesystem.
Understand that if you disconnect the power cable to a motherboard,
drive, peripheral, etc., but not all the other cables (e.g. SATA cable),
you can fry electronics.
Right. This is why power pins are longer than data pins in plug&play
connectors, so that they are connected first and disconnected last.
