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!

Sounds like filesystem corruption. Can you boot singleuser and run fsck?
