As discussed this week, here we remove the explicit permissions file
from udev. All permissions should be specified along with the rule now,
to have only one source of policy.

This simplifies the whole udev process and removes the need to parse a
second file in a different format. The rule file will grow a bit to
apply some permissions, but its an overall win.

You may look at the changes at:
  http://vrfy.bkbits.net:8080/udev/ChangeSet@-8d?nav=index.html

or pull it from:
  bk://vrfy.bkbits.net/udev

or get a tarball including the changes on top of version 050 at:
  http://vrfy.org/projects/udev/udev-050plus.tar.gz


To get this working, the current rules file needs to be updated. I
started to convert the gentoo and the Fedora file available in the tree.
Any help here is appreciated, cause we need to be sure, that it will
work before we make a new release. I've tested both distributions
versions and I'm able to boot and login, but I'm sure there is something
missing.

As an example, the gentoo rules file is attached.

Thanks,
Kay

# /etc/udev/udev.rules:  device naming rules for udev
#
# Gentoo specific rules, based a bit on devfs rules, but much simpler.
#
# There are a number of modifiers that are allowed to be used in some of the
# fields.  See the udev man page for a full description of them.
