Nah, it's a rather ad-hoc definition grown from what should be an Eolie container from the cookbook (also refer to #47097). guix environment --preserve='^DISPLAY$' --preserve=XAUTHORITY \ --preserve=TERM \ --expose=$XAUTHORITY \ --expose=/etc/machine-id \ --expose=/etc/ssl/certs/ \ --expose=/sys/block --expose=/sys/class --expose=/sys/bus \ --expose=/sys/dev --expose=/sys/devices \ --ad-hoc epiphany nss-certs dbus procps coreutils psmisc screen Given that I expose most of /sys explicitly, you should take the above with a grain of salt. > Sorry if my curiosity is making work for you, but I'd like to > try containers down the road -- tho right now I'm taking a break > from events IRL, so I may disappear for a while... I'm not personally impacted by this bug or anything, it's much rather a follow-up to my attempted fix of #47097. I think there might be some flaw in trying to run a sandbox inside a sandbox (like bubblewrap inside `guix container`), that doesn't actually improve security in any meaningful way. Regards, Leo
