UUID in esp-sync.sh script

[Sithuk]

The esp-sync.sh script has an ESPC section that has /dev/sdXX partition identifiers. Can UUID identifiers be used instead as /dev/sdXX is not uniquely tied to a specific partition and is prone to change?

ESPS=(
"/dev/sdb1"
"/dev/sdc1"
"/dev/sdd1"
)

Sure, anything you can pass as the device argument to mount(8) is acceptable.
