From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.6) Gecko/20040116 Description of problem: You can't install or upgrade MAKEDEV (3.9-1) while udev is active, as the preinstall script stops you with an error about devfs. If MAKEDEV and udev are supposed to coexist this is clearly a problem.
one could: %pre mount --move /dev /tmp/dev and after updating /dev %post mount --move /tmp/dev /dev
That introduces a race condition if permissions as set by udev don't match what the dev package contains -- I'd rather not go there.
Supposedly udev and/or initscripts will conspire together to make sure that /dev/MAKEDEV is present, so it can be removed from the package. Because the MAKEDEV package no longer stores anything in /dev, the %pre scriptlet can be removed as well.
