You should try to make this ID unique among your machines. You can

generate a random 32-bit ID using the following commands:

|
|
`head -c 8 /etc/machine-id`
|

(this derives it from the machine-id that systemd generates) or
|
|
|

`head -c4 /dev/urandom | od -A none -t x4`

accidentally on a wrong machine.
