Hello all, just a question, its not a problem, this below in update manager, came up, I expect its all okay, I have been looking it up and reading about it in duck duck go. I must be a fairly important part of the system.
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
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=/bin/systemd or install systemd-sysv in addition.
Packages included in this update: libnss-myhostname libnss-systemd libpam-systemd libsystemd0 libudev1 systemd systemd-sysv udev
