Use any linux distribution inside your terminal.

It manages docker/podman containers to use any linux distro allowing HOME directory of the user, external storage, external USB devices and graphical apps (X11/Wayland), and audio.

1. Share Xorg display

  1. yay xhost
  2. xhost +si:localuser:$USER

Now run any X app in distrobox

2. Create box with init system

For example, ubuntu with systemd to run snapd: 

distrobox create --init --root -i docker.io/jrei/systemd-ubuntu

Very importante the --init

Then just enter: 

distrobox enter --root systemd-ubuntu

And you can verify how you have systemd.

3. Check supported distros

Select one as distrobox create -i ubuntu:20.04
