systemd is a system and service manager that runs as PID 1 and starts the r est of the system. It provides aggressive parallelization capabilities, uses so cket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mou nt and automount points, and implements an elaborate transactional dependency- based service control logic. systemd supports SysV and LSB init scripts and works as a replacement for sysvinit. Other parts of this package are a logging daemon, utilities to control basic system configuration like the hostname, date, lo cale, maintain a list of logged-in users, system accounts, runtime directories and settings, and a logging daemons. This package was built from the 251.10-stable branch of systemd.
