Subject[ANNOUNCE] udev 013 release
I've released the 013 version of udev.  It can be found at:
kernel.org/pub/linux/utils/kernel/hotplug/udev-013.tar.gz

rpms built against Red Hat FC1 are available at:
kernel.org/pub/linux/utils/kernel/hotplug/udev-013-1.i386.rpm
with the source rpm at:
kernel.org/pub/linux/utils/kernel/hotplug/udev-013-1.src.rpm

udev allows users to have a dynamic /dev and provides the ability to
have persistent device names. It uses sysfs and /sbin/hotplug and runs
entirely in userspace. It requires a 2.6 kernel with CONFIG_HOTPLUG
enabled to run. Please see the udev FAQ for any questions about it:
kernel.org/pub/linux/utils/kernel/hotplug/udev-FAQ

For any udev vs devfs questions anyone might have, please see:
kernel.org/pub/linux/utils/kernel/hotplug/udev_vs_devfs

NOTE: The udev.rules file format has changed! If you have a modified
config file it MUST be changed in order to work properly. Here's what
needs to be done:
- The "<METHOD>, " at the beginning of the line should be
removed. <METHOD> is one of the following: LABEL, CALLOUT,
NUMBER, TOPOLOGY, REPLACE.
- The result of the externel program is matched with RESULT=
instead if ID=
- The PROGRAM= key is only valid if the program exits with zero
(just exit with nozero in a script if the rule should not
match)

Also note the following changes in the way the udev.rules file is
processed:
- Rules are processed in order they appear in the file. There
are no priorities anymore.
- if NAME="" is given, udev is instructed to ignore this device,
no node or symlink will be created.

As a result of these changes, we can now create much more powerful rules
by combining multiple key fields. Here's two new rules that show how
you can do this:
# combined BUS, SYSFS and KERNEL
BUS="usb", KERNEL="video*", SYSFS_model="Creative Labs WebCam*", NAME="test/webcam%n"

# exec script only for the first ide drive (hda), all other will be skipped
BUS="ide", KERNEL="hda*", PROGRAM="/sbin/ide-devfs.sh %k %b %n", RESULT="hd*", NAME="%1c", SYMLINK="%2c %3c"

Also, the result of the PROGRAM call is now cached accross multiple
rules as long as a new PROGRAM key is not specified. As an example:
PROGRAM="/bin/echo abc", RESULT="no_match", NAME="web-no-2"
KERNEL="video*", RESULT="123", NAME="web-no-3"
KERNEL="video*", RESULT="abc", NAME="web-yes"
The last rule would match properly.

Many thanks for these changes go to Kay Sievers. I really appreciate
all of the development effort.

If anyone has any problems converting existing rules files, please see
the example rules that are in the udev tarball, and feel free to ask
questions on the linux-hotplug-devel mailing list.

Thanks again to everyone who has send me patches for this release, a
full list of everyone, and their changes is below.

udev development is done in a BitKeeper repository located at:
bk://linuxusb.bkbits.net/udev

Daily snapshots of udev from the BitKeeper tree can be found at:
http://www.codemonkey.org.uk/projects/bitkeeper/udev/
If anyone ever wants a tarball of the current bk tree, just email me.

thanks,

greg k-h
