The Printing Coordinator Services running on your host have some requierments to the used Linux kernel. Mostly, these are required due to run-time restrictions applied by systemd.

Control Group support
Namespaces support
- UTS_NS
- seccomp

Especially it jails the services in the following manner:

run the service as a regular user
restrict system calls to the really required ones
restrict capabilities
limit filesystem write permissions to the CAPS Document Storage Directory
