Yes, I can pound on this nicely with liblxc. We have patch ( https://github.com/lxc/lxc/pull/1728 ) up for review that allocates pty fds from private devpts mounts in different namespaces and sends those fds around between different namespaces. This was one of the original motivations for implementing TIOCGPTPEER. I had marked it as blocked until this bug was fixed which now seems to be the case. Thanks Linus! Christian > > Linus
