Linux UUIDs


When Linux is installed (any distro) does it generate for itself any kind of UUID to uniquely identify the system/installation? I know that there are MAC Address for the NICs, and that individual partitions get UUIDs. Probably a silly idea, but just curious.

On that note: do motherboards have some kind of built-in UUID or identifier that is assessable through an API?

I can't name a program that would give you that info via an api. But you can get the UUID easily enough via the commandline. As root run:
Code:
dmidecode | grep UUID
If you get an error make sure you have dmidecode installed.

Thanks! Amazing how much functionality is on Linux that you never notice until you think to ask.

This is so true If you issue the command dmidecode on its own, you'll get a slew of info about your motherboard and it's capabilities.
