systemd is a Linux initialization system and service manager introduced in 2010 and adopted by default in RHEL 7.0 (2014), that includes features like:
- On-demand starting of daemons
- Inhibitor locks which allows to block or delay system sleep and shutdown requests from the user [1][2]
- Mount and automount point maintenance (
systemd-mount[3],systemd-umount) - Snapshot support
- Processes tracking using Linux control groups (
systemd-cglssystemd-cgtop) - Logging daemon, see
