My laptop's Liteon SSD seems to corrupt early written blocks
when the disk gets near to full. (Or randomly, not sure.)
Preparing to upgrade away from this POS.
(Via full OS reinstall since my OS doesn't track every OS file with hashes, which is kind of ridiculous.)
@liw @joeyh I think it's true that a serious problem in my setup is that I don't have a good way to detect corruption. Probably I can blame that on dumb rsync backups and also using ext4 instead of btrfs. I should probably fix both, and soon.
