Udev on /dev, Udev and selinux

[Ivan Gyurdiev <ivg2@xxxxxxxxxxx>]

I'd like to ask for some help. I'm trying to test selinux, but selinux 
won't work with devfs, so I've decided to finally get rid of it and 
replace with udev. However, that's rather difficult to do.

First, why does the udev startup script declare its own udev_root and 
not respect /etc/udev/udev.conf? Why are the nvidia devices not part of 
the udev startup script (since they're widely used, and not yet in sysfs)?

Secondly, I tried creating static /dev/console and /dev/null so that I 
can even get to the udev script - I placed it at the beginning after 
proc and sys are mounted. However, the root filesystem at this point is 
read-only, and the udev script doesn't create the nodes. I could make it 
run on ramfs, but then how could I make static /dev/console and 
/dev/null? ... and how could I use the selinux policy over ramfs - 
that's why I'm getting rid of devfs in the first place.

Why does the udev stop script proceed to remove my static
/dev/console and /dev/null, which it did not create?

Is there any progress on placing udev in initramfs where it's supposed 
to go eventually?
