From there we could compare the output of ‘find > /sys/xyz’ inside and outside the container, without --expose. Okay, so here's my basic workflow: Starting with an empty set of -- expose: bwrap: Can't find source path /sys/block: No such file or directory repeated a few times along with warnings, that the web process crashed until finally Epiphany itself crashes. I add /sys/block, and Epiphany miraculously doesn't crash, but bwrap still complains and the web processes still crash, so we march on. I'll abbreviate it a little and only show the error messages. bwrap: Can't find source path /sys/bus: No such file or directory bwrap: Can't find source path /sys/class: No such file or directory bwrap: Can't find source path /sys/dev: No such file or directory bwrap: Can't find source path /sys/devices: No such file or directory
After exposing all of the above, I get Unable to init server: Could not connect: Connection refused (WebKitWebProcess:2): Gtk-WARNING **: 10:09:01.497: cannot open display: :1 Using --share instead of --expose for the final set does not seem to change anything. For /sys/block, the find inside the container is empty before exposing it and non-empty on the host. I assume the same holds for the others. Regards, Leo
