The udev-start.sh and udev-stop.sh scripts as supplied by udev could do with a little make over to use some handy features from OpenRC. Use the yesno function instead of testing $VAR = "YES". Use start-stop-daemon to start udev. Use sed and not awk. Try not to hardcode any paths. Stop using the redundant try function. Don't attempt any fstab parsing or have any fancy options. If any are required beyond the defaults then simply add/edit the entry in /etc/fstab. If udev requires any specific kernel version or features, then the udev binary should test for this as it can do a much better job than any shell script. A note has been added to udev-start.sh to indicate this. These scripts should be installed to /lib/rc/addons OpenRC will use them over ones found in /lib/rcscripts/addons

It should be noted that those files are from my amd64 and have /lib64 hardcoded in them - that of course should be adjusted by the ebuild :)
I forgot to mention these are for OpenRC only. They will not work with any baselayout in portage due to missing functions such as yesno and the lowercase variables in play now.
Added scripts based on these to udev-118-r2.
