As I understand > it, only /dev/ptmx and /dev/pts/*, no /dev/tty* nor /dev/pty* ? My FC5 CONFIG_LEGACY_PTYS=n box has no /dev/ptmx, /dev/pts/*, all of /dev/tty0 through /dev/tty63 and no /dev/pty*. I'm not sure where all the /dev/tty*'s came from - perhaps a static udev rule? > - If my setup, for whatever strange reasons has /dev/tty* stored anyware > (/dev/.udev, links.conf...) and they get created, I supose that opening > /dev/tty will give a ENODEV ? well, /dev/tty is attached to your current tty and /dev/tty2 will get you talking to the second VT. I can't immediately thing what /dev/tty22 is attached to.
