/dev/null strangeness

I have a FC4 system that every time it reboots the permissions on
/dev/null change from 0666 to 0660. This causes boot errors and the
system will not boot.

That seemed to me to be a udev error so I looked in:
/etc/udev/rules.d/50-udev.rules
and the mode of null seems correct.

Am I looking in the wrong place or what can I do to fix this problem?

Its probably pam related.
look under /etc/security, but I am not sure that's it

check console.perms

I can see why you would suggest console.perms as the place to look
for a solution to this problem. But:
1. I can find no reference to /dev/null in console.perm related
files.
2. We have ~50 machines with the same copnfiguration of
console.perms and do not have the same problem.

If anyone has further assistance on where to look I would appreciate
it.

I posted the problem stated below and did not get any solutions but a
solution described below showed up.

I mention this so if this happens to anyone else they will know what
the problem was. It was that I managed to create a FC4 system without
a /sys file.

To get this solution I had to use the wisdom of a Volvo mechanic that
I called in a panic. I told him that as I was driving on the
Interstate my gas gage was heading quickly toward empty. He asked the
critical question, "What else is not working?". As soon as I told him
the windshield wipers were not working he diagnosed the problem. A fuse
is blown.

So in this case I asked myself what else was not working? The /media
directory was missing. And so on. I recommend this approach to anyone
else who is faced with similar impossible behavior.
