Subject[ANNOUNCE] udev 016 release
I've released the 016 version of udev.  It can be found at:

rpms built against Red Hat FC1 are available at:
with the source rpm at:

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:

For any udev vs devfs questions anyone might have, please see:

Major changes from the 015 version:
- udev is now in 3 pieces:
udevsend - is called by /sbin/hotplug and bundles up the
hotplug event and sends it off to the udevd
udevd - receives the hotplug messages from udevsend, sorts
them in the proper order, and runs udev for the
different devices.
udev - still the same. Does the actual device node creation
and removal.

This has been one of the major pieces missing for udev, and I
really want to thank Kay Sievers for all of his hard work on

Right now, udevsend and udev are built against klibc (udevsend
is only 2.5Kb big), and udevd is linked dynamically against
glibc, due to it using pthreads. This is ok, as udev can
still be placed into initramfs and run at early boot, it's
only after init starts up that udevsend and udevd will kick

Thanks also 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:

Daily snapshots of udev from the BitKeeper tree can be found at:
If anyone ever wants a tarball of the current bk tree, just email me.
