>Description:
The allscreens_flags is very nice for changing the default syscons
mode. The one thing I dislike about it is that it clears the screen.
This patch doesn't preserve the screen contents, it just introduces
a new /etc/defaults/rc.conf knob called otherscreens_flags that
affects all screens /except/ ttyv0.
We use this in /etc/rc.local, but I thought others might enjoy it.
The ttyv? devices other than ttyv0 are changed with the otherscreens_flags
knob, this preserves the contents of the boot screen, which I find
useful. I can then use the other screens at other modes, say 132x60.
>How-To-Repeat:
Have a boot problem, especially with a RC script, and try to debug it when
allscreens_flags clears the screen on you. :)
>Fix:
Here is a patch to /etc/rc.syscons:
