6.5. mingetty
mingetty is designed to be a
minimal getty for the virtual terminals
on the the workstation's monitor and keyboard. It has no support
for serial lines.
You must not use mingetty for the
serial line in /etc/inittab, but the current
mingetty entries for the virtual
terminals can remain.
Each virtual terminal uses about 8KB of
kernel memory. If this matters, it is easy to allocate fewer
virtual terminals. In the Linux 2.4 kernel virtual terminals are
created on demand, so not starting
mingetty on the virtual terminal will
not create the virtual terminal. If the machine does not have a
video card then remove all the mingetty
entries from /etc/inittab.
After restarting init it would be
wise to remove the unused device files.
