    Add snapd
    
    Snapd is only added to the development tree as a developer tool. The
    services are not started by default.
    
    To enable snapd run:
    ```
    ln -s /dev/null /etc/systemd/system-preset/50-snapd.preset
    ln -s /dev/null /etc/systemd/user-preset/50-snapd.preset
    systemctl preset-all
    systemctl --global preset-all
    ostree admin deploy gnome-os:gnome-os/master/x86_64-devel --karg-append=security=apparmor
    ```
    
    Then reboot.
