Using fgetty instead of getty on Debian
Getty is known to be memory-hungry. Let's replace it with something lighter, which works in most cases: fgetty On Debian Sarge and up, it is already packaged
What is fgetty?
very small, efficient, console-only getty and login
fgetty is a small, efficient, console-only getty for Linux. It is derived from mingetty but hacked until it would link against diet libc to produce the smallest memory footprint possible for a simple yet complete getty.
fgetty includes a login program that supports the checkpassword authentication interface, and also a checkpassword program that uses the standard C library interface to passwd and shadow.
Install fgetty in debian
#apt-get install fgetty
But this is not sufficent for it to be installed instead of getty.You will have to edit /etc/inittab. Warning: this is a very dangerous file to edit, as it may render your system unbootable. You have been warned!
The following lines call getty
1:2345:respawn:/sbin/getty 38400 tty1
2:23:respawn:/sbin/getty 38400 tty2
Lets replace it with fgetty, which takes less arguments:
And do that for as many virtual consoles you would like to have. If you don't need many, comment the lines, but I advise you to keep at least 2.
Save the file and exit.
And then, restart init
# killall -HUP init
