That's exactly what I would like to have! I have a working solution, but using UDEV would seem more adequate. But: I cannot find a serial number for my hard drives in the output. And shouldn't there be a file named 'serial' in /sys? I have some, but not for my block devices, only for USB and in /sys/{bus,pci}/drivers/. BTW, sys-fs/udev-187 does not have the 'udevinfo' command, it seems to be 'udevadm info' now. Wonko
