8 Well, I was talking about if udev was removed and then a reboot was
9 done. I would think it would boot to a certain point then when whatever
10 started and needed devices to be created in /dev, it would start
11 failing. I suspect this would vary depending on the install as well.

40 I get what you are saying and sounds about right. I figure the
41 bootloader would load the kernel and the kernel would do most of the
42 loading until it needed something that udev does. At that point, things
43 start to fail. I'm not going to test this theory tho. ;-)
