It provides aggressive parallelization capabilities, uses socket and D-Bus activation for starting services, offers on-demand starting of daemons, keeps track of processes using Linux control groups, maintains mount 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, locale, maintain a list of logged-in users, system accounts, runtime directories and settings, and a logging daemons. This package was built from the v259-stable branch of systemd. -------------------------------------------------------------------------------- Update Information: More bugfixes.
