Hi Guix, both Epiphany and Eolie (post fixing #47097; will submit patch shortly) fail inside Guix containers with the suggested incantation. After getting the environment to no longer complain about $DISPLAY by adding `--preserve="XAUTHORITY" --expose=$XAUTHORITY', it repeatedly outputs lines like bwrap: Can't find source path /sys/class: No such file or directory before closing the process altogether.
Regards, Leo
