Systemd Linger
Summary
Systemd Linger discusses keeping user processes alive after logout using systemd's linger feature and the KillUserProcesses setting. It includes practical commands to enable or disable linger (loginctl enable-linger / loginctl disable-linger) and notes the lack of a simple way to list which accounts have linger enabled. The post also shares real-world anecdotes from Debian, KDE, and SE Linux testing, highlighting both benefits (e.g., background services starting before login) and caveats.
