===== Notes =====

UUIDs are 16-byte values stored in network byte order as defined by [[https://datatracker.ietf.org/doc/html/rfc4122|RFC 4122]].  Some software treats UUIDs as being stored in little-endian byte order.  You can format a UUID in little-endian byte order using the ''[[:cfgtype:guid]]'' setting type.
