[LUNI] UDEV rules ... SYSFS{serial} value?

[David Gibbs]

folks:

Does anyone know how to give a drive a SYSFS{serial} value so that I can
setup udev rules to automatically recognize a USB drive when it's installed?

I've found that some drives have a SYSFS{serial} value ... but others
don't.  The serial number seems to be a pretty good method of
recognizing unique drives when they are installed.

Thanks!
