Can't run jobs in background in the container.

[yeban]

If user's login shell is bash (or neither bash, zsh, or fish and hence bash is executed in the container), following is printed to the terminal at launch.

bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell

Subsequently execute:

sleep 10 &
fg
bash: fg: no job control

While zsh doesn't complain when launching, job control is disabled in zsh too. (Run sleep 10 &; fg).

This happens because of -c switch to su (_init:L13). See http://serverfault.com/a/605465.

Sorry @yeban - tty stuff is still failing

That's because the image doesn't get rebuilt on your system. I'm thinking how to make it happen. Temporarily can you run docker images, look for image called 'switch/biolinux' and 'switch/baseimage', delete them by docker rmi <id> and run bundle exec bin/switch biolinux again? :|

[yannickwurm]

Trying (its a bit rebellious); wouldn't changing version of your docker image lead to new creation?

[yannickwurm]

Confirmed - erasing all images (required stopping/deleting containers first) - then recreation of new biolinux image works
