I'm not against doing it with udev, but it's not a lot of extra code either way. > You would need some tool to obtain the vpd data from user space that would > always be installed. Yes. I've been using sg_inq from sg3_utils to play with it, but one could write a specialised tool very quickly. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
