Konstantin Khlebnikov	8b253b07e9	TTY, devpts: document pty count limiting ... Logic has been changed in kernel 3.4 by commit e9aba5158a ("tty: rework pty count limiting") but still not documented. Sysctl kernel.pty.max works as global limit, kernel.pty.reserve ptys are reserved for initial devpts instance (mounted without "newinstance"). Per-instance limit also could be set by mount option "max=%d".
