These are 20 Pi's, that only run Folding@home.Ahh...useful information that you've cloned these.
A single Pi was set up from an SD card with customisations, and then uploaded to the NAS using rsync. Files were changed to allow network booting. This system was used to create the other systems (20 clones of one system) using rsync. The cloned file systems were updated using sed. These changed the hostname in /boot/firmware/cmdline.txt, /etc/hostname, /etc/hosts and /etc/fstab (to mount to boot directory), and the IPv4 address in /boot/firmware/cmdline.txt and /etc/NetworkManager/system-connections/Wired connection 1.nmconnection.

It's very frustrating because the Pi's are working fine (once Network Manager is started).
Could setting up each Pi using a fresh copy of the image, or using SDM resolve this problem?
