What is the system and service manager on our Fedora VMs? How can you verify that on your system? What version of Linux is running on fawad, and what is it's system manager? What the the commands to find the system and service manager on Fedora Linux?

Answer:

Systemd is a system and service manager for Linux, compatible with SysV and LSB init scripts. It provides such as an

First, Aggressive parallelization capabilities

Second, Uses socket and D-Bus activation for starting services

Third, Offers on-demand starting of daemons, keeps track of processes using Linux cgroups

Fourth, Supports snapshotting and restoring of the system state

Fifth, Maintains mount and automount points

Last but not the least is to Implements an elaborate transactional dependency-based service control logic. 

  The command to see the status is use this # systemctl status foo. 

   The system manager is a first process which start on your Linux system. Thus looking at what processes started first by using ps -p 1 command my provide some clues, but no definitive answers (https://linuxconfig.org/detecting-which-system-manager-is-running-on-linux-system#:~:text=The%20system%20manager%20is%20a,clues%2C%20but%20no%20definitive%20answers.) That is the reference. 

   Use ps-p 1 command like this SysV
# ps -p 1
 PID TTY          TIME CMD
   1 ?        00:00:01 init
Systemd
# ps -p 1
 PID TTY          TIME CMD
   1 ?        00:00:04 systemd
Upstart
# ps -p 1
 PID TTY          TIME CMD
   1 ?        00:00:01 init 

First what is Fedora Linux, is a suite of basic building blocks for a Linux system. Its called systemd not System D or even SystemD why? because it's a system daemon and under LINUX/UNIX. This control groups, maintain mount and automount points and implement an elaborate transactional dependency-based service control logic systemd supports SysV and LSB init script. The daemons manage simple network configuration, network time and synchronization, log forwarding and name resolution.
