No, in fact, the second link said that GUIDs are part of an ISO standard
(ISO-11578) which specifies the DCE-RPC (Distributed Computing
Environment-Remote Procedure Call) which is a cross platform specification.
Here's the description of the uuidgen tool on Linux (copied from the Linux
manual at linux.com)
"The uuidgen program creates a new universally unique identifier (UUID)
using the libuuid(3) library. The new UUID can reasonably be considered
unique among all UUIDs created on the local system, and among UUIDs created
on other systems in the past and in the future.
There are two types of UUID's which uuidgen can generate: time-based UUID's
and random-based UUID's. By default uuidgen will generate a random-based
UUID if a high-quality random number generator is present. Otherwise, it
will chose a time-based UUID. It is possible to force the generation of one
of these two UUID types by using the -r or -t options."
