I'm not thinking about anything specific, I'm simply disputing your general claim that moving away from C would not help, when it has clearly helped in every single other domain of software development. I see no real reason why file systems should be any different, but clearly you do, so I was asking you why you think file systems would be different.

And for specific examples of options with better safety records, then sure Rust would be one possibility, as would Ada, or Frama-C if you need to stick with C.
