I used simple one. Only gentoo's stage 3 unpacked into a directory, no special settings used for it. Removing /etc/securetty works for me. I'll give it another try, but probably after the freeze.

I tried with latest master with and without your patch. Wtih your patch I got to the problem exactly once even though I tried multiple times. And even though it didn't happen to me at all without your patch, I'm thinking it's just some weird rare race and it's not related to what you've sent. That just wouldn't make sense to me. I also suspected the problem being me starting with --console parameter, but trying with and without that didn't help isolate the problem either. Anyway, that patch still doesn't help me get rid of /etc/securetty. The output of 'tty' is still /dev/pts/0 and unless I remove /etc/securetty it doesn't start. What is the output of 'tty' and what ttys do you have in /etc/securetty in your container?
Can you share your xml?
Sure, mine is almost same as yours except the user namespace
isolation.
