I have a set of environment variables that I need to be globally set for all users and all systemd services.  I don't want to have to specify them it two different locations.I tried setting them /etc/environment and /etc/profile.d.  These both worked, but only for logged in users, not systemd services.  I tried setting them /etc/default/init and that didn't work for any process.How can I set environment variables globally for all users and all services without having to specify them redundantly in multiple locations?Distribution: Raspbian
