As others have said, this is not possible. It is however possible to configure it via a dropin file.
e.g. if your unit is called foo.service, then just mkdir /etc/systemd/system/foo.service.d/ and create a file cpu-affinity.conf inside that folder (any filename will do). In this file put: [Service] CPUAffinity=0-2 Then just reload systemd (systemctl --system reload) and your value should be available. It's not an environment file, but it's still an easy file for administrators to hack on without affecting packaged units in /usr Note, to make life easier for you, you can simply call "systemctl edit foo.service" and an editor will open and let you customise it.
