This is still a hack.
Something is wrong with permissions upstream. They document 777 as the
solution but that should never be a solution. I think I want to explore
the container build, especially since the permissions error is reported
on github issues #10. They provided an unrelated fix to UID inside the
container, but it didn't help about 777.
This is currently incomplete. The volumes mount and weechat launches,
but it is flooded with permission errors when trying to set up.
Might mount them all individually just to see what happens but that's
probably not a sustainable idea going forward.
