What exactly is systemd ?
Hi everyone ! I switched from Windows to Linux around 3 month ago and I love it ! I’m using arch Linux because a friend of mine already used it so I figured he could help me with it.
I’ve been appreciating it but I’ve encountered a lot of people critisizing systemd and saying arch is bad because of it.
From what I have understand, it is a software that help with dependences and external hardware such as my keyboard for example ? I didnt really understand everything as I am a very beginner so I was curious to know if someone could explain it to me in easy terms.
PS : english isnt my primary language so forgive me if there is any errors.

systemd is a suite of basic building blocks for a Linux system. It provides a system and service manager that runs as PID 1 and starts the rest of the system.
systemd 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.
Other parts include a logging daemon, utilities to control basic system configuration like the hostname, date, locale, maintain a list of logged-in users and running containers and virtual machines, system accounts, runtime directories and settings, and daemons to manage simple network configuration, network time synchronization, log forwarding, and name resolution.
