But the bug hasn't been clearly identified, so my paranoid approach to kernels would keep me off of it. (On production systems, of course. I regularly run -rc kernels on my laptop.) >> I'm guessing that /dev/sda contains your boot and root filesystems, and that >> this isn't an error. > > You are correct, sorry I did not mention that initially.

The output will change substantially, as it attempts to map the entire storage tree, reporting all serials, uuids, and labels, along with other useful information. I have a future number of enhancements in mind, but it's a spare-time project. I'm glad you like it, though. You don't need the report for this incident, though. Just stick it with your backups. And make a new one any time you change your setup.
