[ANNOUNCE] udev 010 release

[ANNOUNCE] udev 010 release

[Greg KH]

I've released the 010 version of udev.  It can be found at:
 	kernel.org/pub/linux/utils/kernel/hotplug/udev-010.tar.gz

rpms built against Red Hat FC1 are available at:
	kernel.org/pub/linux/utils/kernel/hotplug/udev-010-1.i386.rpm
with the source rpm at:
	kernel.org/pub/linux/utils/kernel/hotplug/udev-010-1.src.rpm

udev is a implementation of devfs in userspace using sysfs and
/sbin/hotplug.  It requires a 2.6 kernel to run.  Please see the udev
FAQ for any questions about it:
	kernel.org/pub/linux/utils/kernel/hotplug/udev-FAQ

Please read the FAQ if you have any questions about devfs and udev.
It's been updated a lot in response to all of the confusion about this
topic.

The major changes since the 008 release are:
	- a number of bugs that were in the 009 release are now fixed.
	  The extras/ subdir should now build properly (but I take no
	  responsibility if it doesn't...)
	  
	- we now don't blow away old config files if you install this
	  version on top of an older version.  Sorry about that...
	  
	- udev now supports looking at multiple sysfs files at once for
	  a single rule.  This enables you to write such rules as:
	  LABEL, BUS="usb", SYSFS_vendor="FUJIFILM", SYSFS_model="M100", NAME="camera%n"
	  which helps in trying to identify a device in a unique way.
	  Right now udev supports up to 5 different sysfs files.  If you
	  want to have more, the code can be changed, just let me know.

	- new format modifier "%k" has been added to allow rules to use
	  the kernel name of the device.

	- an example shell script that handles an IDE devfs mapping has
	  been added to the tarball.  Thanks to Kay Sievers for this.
	  
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 this tree used to be found at:
	http://www.codemonkey.org.uk/projects/bitkeeper/udev/
But that box seems to be down now.  Hopefully it will be restored
someday.  If anyone ever wants a tarball of the current bk tree, just
email me.

thanks,

greg k-h

Oh, forgot to mention that udev runs a _lot_ slower now, taking at least
1 second for every device addition.  This makes the initscript or the
test scripts take a long time.

This was done to try to fix the race condition where udev beats the
kernel before it has created all of the sysfs links and files.  I need
some libsysfs changes before this can be done properly, without the big
speed hit (the libsysfs people are working on it.)

If anyone's interested in it, take a look at the FIXMEs in namedev.c.
I tried messing around with just a simple stat() call, but still
couldn't reliably get stuff to work for partitions on usb-storage
devices (which are slow to enumerate.)  Any help here would be
apprecated.

thanks,

greg k-h
