I tried patching webkitgtk to share the whole /gnu/store in the new mount 
namespace (see attached patch). Unfortunately, when I ran epiphany with 
that patch applied and PULSE_CLIENTCONFIG set to /etc/pulse/client.conf, 
the "bwrap: Can't create file at /etc/pulse/client.conf: No such file or 
directory" error returned.

Via strace, I saw that my patch was having an effect on the arguments to 
bwrap. Could it be that the order of the --bind/--ro-bind arguments 
matters?

Thoughts?
