Replace Neofetch with your own Linux MOTD system

Neofetch is abandoned, but you can build a custom Linux MOTD system from scratch using Bash and systemd. The tutorial covers writing a Bash script that uses hostnamectl to gather system info and formats it into /etc/motd, then automates updates with a systemd service and timer running hourly. Key concepts include why the timer should be enabled while the service stays disabled, using OnBootSec to delay initial execution, and optionally appending a fortune joke. The result is a self-updating login message showing hostname, OS, kernel, and architecture.
