Then the typical usage from the systemd-nspawn man page:

systemd-nspawn [OPTIONS...] [COMMAND

Is a bit flawed, no?


Not sure what you are suggesting I should do instead. Run as -b and boot
into systemd first? That is annoying since then I need to login, setup
DISPLAY env again (not sure why) and then manually run firefox. Wish it
was one step! :)

That said running with -n doesn't seem to work without -b since
systemd-networkd needs to setup the container's networking, no ?

sudo systemd-nspawn --setenv=DISPLAY=:0 \
               --setenv=XAUTHORITY=~/.Xauthority \
               --bind-ro=$HOME/.Xauthority:/root/.Xauthority \
               --bind=/tmp/.X11-unix \
               -D ~/containers/firefox \
               -n  firefox # doesn't work since systemd-networkd isn't
               being run IIUC
