If udev does not create the directory itself (I can't imagine that it does), then the directory needs to be created by something; either the script (by adding it to /lib/udev/devices) or an explicit mkdir (with proper permissions) somewhere after the udev script mounts a tmpfs on /dev. > Without it terminal emulators (roxterm, gnome terminal) won't work for me. Yes; anything that requires unix98 PTY support requires this. Terminal emulators, screen, expect, etc., all need it. (Unless the kernel support has changed lately, such that the normal udev infrastructure handles the creation of the pts/* files. But I doubt it, since there are tight timing requirements on the API here, requiring the pts/* file to be present before the syscall on the /dev/ptmx FD that the program has open finishes. See the pty(7) and ptmx(4) manpages.)
