Trouble getting this to work...

[thandal]

I tried both head, and pull request #3, each fail in similar but (to me) cryptic ways. Any suggestions would be appreciated!

I'm running under Ubuntu 18.03 (under WSL2, if that's relevant).

Head: $ docker run --rm -it xena/docker-uml [WARN tini (8)] Tini is not running as PID 1 and isn't registered as a child subreaper. Zombie processes will not be re-parented to Tini, so zombie reaping won't work. To fix the problem, use the -s option or set the environment variable TINI_SUBREAPER to register Tini as a child subreaper, or run Tini as PID 1.
