Yep, the securetty file is one of only 2 remaining blockers for getting login working out of the box in containers. Removing securetty would be a great help there given the inability to wildcard pts/*. The other problem is of course the horrible pam audit module, which the kernel guys are hopefully working towards a solution for.
