FYI,

I added several patches to udev-039 which will be on FC3.
I only describe the most patches here. The patches itsself are in the src.rpm and can be posted on request.
The two relevant and important patches against 039 are attached.

****

Patch1: udev-039-static.patch
makes inline getpwnam and getgrnam functions, which are used for the static version of udev, which is used in initramfs

Patch2: udev-025-volsbin.patch
moves volume_id from /usr/sbin to /sbin (such tools should not live in /usr, because /usr could be nfs-mounted

Patch3: udev-039-wait-error-log.patch
wait_for_sysfs patch

Patch4: udev-039-logging.patch
logging patch

Patch5: udev-039-wait-ppp-class.patch
wait_for_sysfs patch

Patch6: udev-039-wait-dm-block.patch
wait_for_sysfs patch

Patch7: udev-039-static2.patch
include wait_for_sysfs in udev for the static udev version used in initramfs

Patch8: udev-039-netif.patch
only call dev_d_send for network interfaces, if the name was changed

Patch9: udev-039-dummy.patch
wait_for_sysfs patch

Patch10: udev-039-volume_id-nonblock.patch
do not open(2) with O_NONBLOCK

Patch11: udev-039-norm.patch
add NOREMOVE keyword to the rules. this was necessary because removable ide devices were added/removed for every open(2)/close(2)
added to the rules:
KERNEL="hd[a-z]*", NOREMOVE="1"

this could eventually be refined by checking the "removable" sysfs-attribute, but not for partitions..

Patch22: udev-032-symlink.patch
replace format directives in every symlink part

Patch24: udev-038-volmak.patch
Makefile patch for volume_id
