Well, here is a decent tradeoff... [/usr/src/sys/i386/isa/syscons.c]
#define HISTORY_SIZE 60 * 80 * 5
^^------- or 132
Granted, those with 4 megs may want to use a lower number depending on
the number of vty's... I'm running with 20 megs, so this is no big deal
for me, I could go larger, but I personally feel that any major
scrollback function belongs in the shell anyhow.
Also, has the problem with the screen trashing when you come out of the
scrollback sometimes been fixed? I think I mentioned this in -hackers
some time back...
