As soon as you have to enable a a deamon/service, you have to interact with systemd. Systemctl is the command that is used for that (with option enable, disable, start, stop and restart)

Some programs require you to enable such a service, in order that they work, but would not talk about systemd while explaining install of xyz, more like “enable xyz: sudo systemctl enable xyz”.

Thats's intresting. I only use linux as vms, or on ny android Termux interface, since 4 months and i could install arch with archinstall and nowadays i'm almost done it without archinstall. I will also plan to write my own "bootloader" if grub and systemd-boot acts up, which grub did. I also wrote this script that creates a log file from your open ports using nmap and saves it with the current date:

clear ; pkg install nmap && sudo nmap -O 127.0.0.1 >> "log$(date +%Y%m%d-%H).txt" && echo "/n/nlog file saved to $(pwd)/log$(date +%Y%m%d-%H).txt" ; nano "log$(date +%Y%m%d-%H).txt"
