Five ways to free up rootfs in Arch Linux

1. Cleanup Pacman cache

   paccache -k 0 -r
   

2. Cleanup orphan packages

   pac -Qtd
   

3. Cleanup journal

   journalctl --vaccum-time=1w
   

4. Set max disk capacity for journals
   • Change SystemMaxUse to 100M in /etc/systemd/journald.conf

   • Then restart journald service

     sudo systemctl restart systemd-journald.service
     

5. Use ncdu to see which file uses most of the disk
   • Cleanup unused fonts
