Comment 4 for bug 1551960

I locally applied https://github.com/lxc/lxc/commit/12752e2 to our current package and built it. Now it looks better:

# lxc-attach -n a runlevel
N 5
# lxc-attach -n a runlevel </dev/null
N 5
# lxc-attach -n a runlevel </dev/null 2>/dev/null
N 5
# lxc-attach -n a runlevel </dev/null 2>/dev/null | cat

So redirecting stdin only now does not show this "lxc_console_cb_tty_master: 683 Bad file" error any more, and redirecting stderr now works too. But redirecting stdout in addition still doesn't?

Maybe I'm missing another fix from trunk, though.
