Docker: screen should start a bash session

[bschmalhofer]

Whenn logging into a otobo_web_1 container with docker exec -it otobo_web_1 bash one gets into bash. Running screen gives you /bin/sh. I would have expected /bin/bash . as $SHELL is /bin/bash . There is no /opt/otobo/.screenrc and no obvious setting in /etc/screenrc . screen -s /bin/bash works fine.
Adding /opt/otobo/.screenrc with "shell /bin/bash" should do the trich, but it would be nice to understand the behavior.

Found no good solution, so I'll add a ~otobo/.screenrc file. At least other people had the same problem: https://askubuntu.com/questions/721092/default-environment-for-screen-is-bin-sh-when-it-should-be-bin-bash.

Adding .screenrc did the trick. Closing this issue.
