That's all. I just found this in a random script. Generates a random UUID every time it's called. I didn't know.

Of course I can also use uuidgen or pipe /dev/(u)random into something to get a random alphanumeric string - but this is built right into the kernel!

In /proc/sys/kernel/random/, there's also boot_id which ~~seems to do the same~~ is static, and some tweakable parameters.

The information will be evenly distributed upon its surface and some believe one day it will be be radiated back out into the rest of the system.

That's a horrifying concept. Better not think about it.
