System and service manager
  1 review

Systemd is a system and service manager for Linux. 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 is compatible with SysV and LSB init scripts and can work as a drop-in replacement for sysvinit.

Installing the systemd package will not switch your init system unless you boot with init=/lib/systemd/systemd or install systemd-sysv in addition.

my boot time to graphic login used to be 18s. With systemd installed it varies between 52 s and 600s. Detailed look, by editing the grub boot line to drop the 'splash' so I can see what is taking so long, reveals that systemd, far from speeding things up by massive paralellization, just does everything all over again, slower by at least a factor of two. If I needed this, I'd go to Windows! The justification for this overload of the iron is that users won't be mature enough to get the updates performed. That babying belongs to MicroSoft! Linux is not to have the 'hood welded shut', so to speak.
