> How can I reproduce it?

On the host:

lxc launch ubuntu-daily:groovy foo

Then if "lxc exec foo runlevel" says "unknown" after 10 seconds, the problem is reproduced. When it does so the command has an exit status of 1. If it says "N 5", then the problem didn't occur, and the command has an exit status of 0 in this case.
