I integrated udev with Fedora Core. The main piece is simply building /udev on boot, since we don't have an initramfs yet. We should also clear out /udev on shutdown, for /udev directories mounted on persistent media. The attached script goes in /etc/init.d Then do "chkconfig --add udev" And the rest is handled automatically. I made it for Fedora but it will probably work, with little change, on any Linux system. Right now it only does sysfs-based discovery of block and tty devices, since those are the only types of devices I have on my system. There is a TODO in the script where we would add the other device types.
