mknod - how do I make a device re-appear after re-boot

[Steve Turnbull <steve.turnbull@yhgfl.net>]

Hi

My setup: Debian unstable, KDE3.3, Sony Vaio VGN-A217M laptop

I need a device in /dev/ called sonypi which is required for my Sony
Laptop FN keys etc.

I run this command as root;
mknod /dev/sonypi c 10 63

This works fine, and when I run my startup script for the sonypid
module, the FN keys work as well.

The startup scripts are all fine and are linked to correctly from rc5.
The problem is that when I reboot my laptop, the sonypi device in /dev
is no longer there.

My question is: how do I make the /dev/sonypi device permanent?

I don't know what more information I could provide? Please say if there is...

Regards
Steve
