After watching Michael's talk on diskctl and knowing a bit about the differences between NVMe and ATA SMART data, I was curious how something like the libsmart proposed in the talk could possibly work. This tool was initially a test bed for those experiments, but it's been cleaned up a bit and enhanced based on Michael's feedback. The application works with the limited number of drive types we have, and the hope was both to see how it fared on other folks drives as well as get some feedback. This work wasn't done for any particular vendor. The only hope was to address a need voiced by someone in the *BSD community. Namely, providing SMART values to other scripts and or applications. As far as adding this to base, if the collective 'you' want it, awesome. If it doesn't make sense, that's OK too. --chuck
