Quickstart and permissions

I was just following the quickstart from the readme with the prebuilt docker image.

$ ./scripts/run-container sites/example /foo/bar
marv-robotics
marv-robotics

I guess the issue is that sites/example is not writable by user with id 1000, which is the case for our lab setup with ldap users. A workaround is chmod -R a+w sites/example/, but that is maybe not ideal.

Not sure what the best workflow is here... What we did in the past was changing the user id of the marv user on container startup to match the user id on the host.
