I'll test that.

Edit: OK, so I created a Debian VM, noted /etc/machine-id, deleted it, and rebooted. And found that it was still missing.

Running systemd-machine-id-setup generated a new machine-id from the D-Bus machine ID. And it was the same as the initial one.

But I also see in man machine-id:

> The machine-id may also be set, for example when network booting, by setting the systemd.machine_id= kernel command line parameter or passing the option --machine-id= to systemd. A machine-id may not be set to all zeros.

Does something like

dd if=/dev/urandom bs=1 count=16 | hexdump

Give you something that you can use?

Well, the machine-id of that Debian VM was ...

    38d05397c25548b4f4bda7751b5062
... and ...

    $ FOO=`cat /dev/urandom | tr -dc a-z0-9 | head -c${1:-30}`
    $ echo $FOO
      6we4gvnmx00w208ffty6i11m82rw6d
But I have no clue whether systemd would be happy with that. Maybe later I can test more.

Edit: Oops. Make that ...

    $ FOO=`cat /dev/urandom | tr -dc abcdef0-9 | head -c${1:-30}`
    $ echo $FOO

Maybe use pwgen?

Something like:

    $ pwgen -1s 31

I think that it needs to be hexadecimal. But not sure.
