FileSystemException on Docker container

See original GitHub issue

Hello. I caught following FileSystemException on Docker container.

$ docker exec 6dd java -jar /usr/local/bin/digdag run /mydag.dig
2017-06-23 06:54:52 +0000: Digdag v0.9.12
error: java.nio.file.FileSystemException: /proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/self/task/178/fd/24/proc/1/map_files: Operation not permitted (directory iterator)

digdag run command lists files on the current directory and it traverses subdirectories recursively. When you run digdag run in docker container, probably it ran on /. /proc is a subdirectory of / and apparently it includes recursive symbolic link: /proc/self/task/178/fd/24 -> /. So listing up files recursively caused infinite loop.

You should be able to avoid this problem by using another working directory.
