I was afraid of this finger-pointing. Of course no one at Debian is going to know how to fix BTRFS jamming the package management system. That's ridiculous. It's starting to look like BTRFS is just busted in Debian, and I'll have to reinstall everything over a different filesystem. I hate to

I know what the error says; we've established that / is in fact mounted. The system boots and runs, but grub doesn't understand it. My only answer is that grub-probe does not understand BTRFS. The question is what to do about this. I have three major systems committed to this filesystem.
