Real terminal login

Operating systems provide a range of devices that are real terminals, or things pretending to be real terminals, attached via serial ports (and possibly modems). This package contains tools for running and managing TUI login services on real terminals. It also contains pre-written service bundles for such TUI login services.

Login on real terminals is done with ttylogin services, configured to use those devices. They are always alias names for other services, that are in turn named after the serial-line "getty" programs that they employ (such as getty, mgetty, and agetty).

Such a TUI login service is a very simple service, which can be managed just like other ordinary services, started and stopped and enabled and disabled in the usual way. There is one augmentation to ordinary service management: the preset command uses the ordinary preset file mechanism, but can also read the /etc/ttys file.
