I think I am missing some basic bit of configuration lore. I hacked my kernel to change the font size selected by rasops, but I would like to make a proper configuration interface for it, something like an integer that biased the default size calculation.
It would be nice to be able to use /etc/wsconsctl.conf to set it, but screens can't be reconfigured after they are created (I want to fix that in the future), and it would be better to have it take effect on console startup, well before anything else gets loaded. It feels like what I want is an integer variable that can be set to a default in the kernel config file, then modified on an existing kernel with config(8), or temporarily overridden with a parameter from boot(8). I see how I can make a numeric option in the config file, but it just turns into a #define that can't be modified. Is there any facility like this?
