>From 'man 5 machine-id' on my Fedora box:

The /etc/machine-id file contains the unique machine id of the local
system that is set during installation...

The machine ID is usually generated from a random source during system
installation and stays constant for all subsequent boots. Optionally,
for stateless systems it is generated during runtime at boot if it is
found to be empty.

As for what uses it, and why, I'm still not quite sure.

BUt now I've got to figure out why an LFS build doesn't generate/install
that man page!

Pierre, r10187 should fix up the systemd install/post-install tagging.
If there's anything else causing package management issues, just let me
know, and I'll be happy to fix them up.

Regards,

Matt.
