Clearing the Machine ID of a Cloned Instance for DHCP
Photon OS uses the contents of /etc/machine-id
to determine the DHCP unique identifier (duid) that is used for DHCP requests. If you use a Photon OS instance as the base system for cloning, to create additional Photon OS instances, you must clear the machine-id
with this command:
echo -n > /etc/machine-id
When the value is cleared, machine-id
can be regenerated by calling systemd-machine-id-setup
.
systemd-machine-id-setup
This command initializes the machine ID stored in /etc/machine-id
during installation. For more information on this command, see https://www.freedesktop.org/software/systemd/man/systemd-machine-id-setup.html.
