bocker exec fails

Bocker exec fails always, it just outputs a long list of increasing integers. Am I doing something wrong, or is this a bug? I can't find any documentation about exec. All the other commands are working.

What is still not right?

Sorry, I mean I thought 11129ae would also fix the exec issues, but it didn't. Exec still isn't working once the original process dies.

Ok so there are two issues here.
Start a container:
bocker run img_42078 "while :; do echo 'foo'; sleep 5; done"
Try and exec a command with multiple words = FAILS:
bocker exec ps_42201 ps aux
chroot: failed to run command ‘ps aux’: No such file or directory`
Try and exec a command with one word = WORKS:
bocker exec ps_42201 bash
ps aux
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 1 0.0 0.2 11116 1392 ? S+ 18:31 0:00 /bin/sh -c /bin/mount -t proc proc /proc && while :; do echo 'foo'; sleep 5; done
root 8 0.0 0.1 5884 612 ? S+ 18:31 0:00 sleep 5
root 9 0.0 0.3 13344 1952 ? S 18:31 0:00 bash
root 22 0.0 0.2 21364 1376 ? R+ 18:31 0:00 ps aux
Ctrl-C the bocker run
command and then try to re-enter it = FAILS:
bocker exec ps_42201 bash
nsenter: failed to parse pid: 'PID
1
2
3

24106
24107
So what needs doing here is:
- Correctly quote and pass arguments into the container when exec'ing.
- Throw an error if the container is not running.
