Description

Attempts to map a host folder to the internal container folder

/root/.guacamole

fails with the following error message: 

rm: cannot remove '/root/.guacamole': Device or resource busy

We have tried to create the instance with guacamole/guacamole and guacamole/quadc on several different host computers using both Docker run, Docker Compose as well as Portainer. The result is always the same error message.

Using ozru/guacamole image works, so we assume there is a bug in the guacamole/guacamole cotainer image.
