As a test, it just increases our code coverage in a fake way. When run manually, it can be used to conveniently print what logind thinks about various processes: $ build/test-sd-login sd_pid_get_session(0) → No data available sd_pid_get_unit(0) → user@1000.service sd_pid_get_user_unit(0) → app-ghostty-transient-5088.scope sd_pid_get_machine_name(0) → No such file or directory sd_pid_get_slice(0) → user-1000.slice sd_pid_get_user_slice(0) → app.slice sd_pid_get_owner_uid(0) → 1000 sd_pid_get_cgroup(0) → /user.slice/user-1000.slice/user@1000.service/app.slice/app-ghostty-transient-5088.scope/surfaces/556FAF50BA40.scope $ build/test-sd-login cgroup 1 sd_pid_get_cgroup(1) → /init.scope
