devfs, input event system, and kernel configuration.

Hi,

I am trying to attach a special serial input device to an X application.
Looking at the kernel document, it seems to me the input core system (the
/dev/input/event#) fits the my needs nicely. I also realize that the input
system uses the devfs rather than the traditional major/minor number for its
device driver.

So I configured a 2.4.18-5 kernel with the following flags turned on,

        - devfs turned on,
        - the input core module,
        - the input core's keyboard and mouse modules
        - the input core's event modules

The kernel compiles fine. However, during boot process, everything under
the /var/* and several device mounts were marked as read-only and thus the
kernel fails to boot. I tried to set the devfs=nomount as its boot
parameter. It didn't help either.

Thanks in advance!
