I agree head -c 8 /etc/machine-id makes more sense.
1. Simplify the command by reading directly from /etc/machine-id which is already a random, lower-case hex string 2. Previously, the command output could be too short because of missing leading digits. This is now fixed.

Pad the hex literal with leading zeros to the required length of 8 bytes (32 bit).
Question to reviewers:
As
/etc/machine-idis already a random, lower-case hex string, why not just usehead -c 8 /etc/machine-id?
