I know there are some tools including firejail and bindtointerface on standard Linux Distros, but they don’t run in userland, so whenever the deck updates they will be overwritten.

Anyone have any ideas how to block access on a Steam Deck?

    That is correct. The best case is to write a script to make your desired changes, and then run it after each system update.
    My own use-case is that I have a NFS mount-point for my Steam Deck to use extra storage on my NAS. After the first time I figured out how to get it mounted, I made a script to disable read-only filesystem, make all the changes to the system, and then re-enable read-only filesystem. After every system update, I just run that script once.

      Thanks for the reply!

      I can find my way around bash, but the most advanced script I’ve personally authored it probably “Hello World.” Would you be willing to share the script from pastebin or github? IDK, I guess you could copy and paste it posted on Lemmy.

      I think I need to do exactly what you recommended, but I may need some help setting it up. So are an update, you simply run the script to get the system changes re-applied?

        This is the script. /home/deck/scripts/fstab contains my customised fstab file. Yes, after an update, I just run this script once.

        #!/bin/bash
        
        if [ ! -f ~/.config/kdesurc ];then
          touch ~/.config/kdesurc
          echo "[super-user-command]" > ~/.config/kdesurc
          echo "super-user-command=sudo" >> ~/.config/kdesurc
        fi
        
        if [ ! -f /var/mnt/nas ];then
          sudo -c 'sudo mkdir "/var/mnt/nas"'
        fi
        
        sudo cp -a /home/deck/scripts/fstab /etc/fstab
        sudo steamos-readonly disable
        sudo pacman -Syy
        sudo pacman-key --init
        sudo pacman-key --populate
        sudo pacman -S --overwrite "*" nfs-utils
        sudo steamos-readonly enable
        sudo mount -a
