100000% agree. Alas, FFS's whole schtick is caring about drive geometry, so we kind of need to fake up something for newfs on such drives (and we should do it in a generic way so the code isn’t replicated in a million different places), and have some way of getting the real info for drives where it actually does exist. -- thorpej
