Optimising the detection, good.

Maybe, but I'd discourage people from turning it off more strongly, as it's a
small price to pay for peace of mind.

So, after review and a bit of tweaking, yes, I'm in favour.

However, the whole of this code is itself 'legacy' in that this detection is
moving into blkid under udev's control, so you should check if that code is
sufficiently efficient too.
