Subject: [PATCH] docs: remove /dev/tty* confusion
The text said /dev/tty* as a whole was the VT subsystem and that VT is
not supported in containers.
But that's not accurate as /dev/tty* will match /dev/tty too and that
one device node is special and is not related to VT: it always points to
the current process own controlling tty, regardless what that is.
hence, rewrite /dev/tty* as /dev/tty[0-9]*.

Hence, it is explicitly not OK to mount a pty to `/dev/tty1`, `/dev/tty2`,
`/dev/tty3`. This is explicitly not supported.
