I did some digging. Seems the "crash-only" model has been applied mostly
to application development rather than file systems. Exactly one
"crash-only" file system was ever developed for Linux, and it was later
deprecated in favor of BTRFS by its author, Valerie Henson-Aurora. It
seems the REAL gremlin at work in the woes I described may be write
caching. Could "hdparm -W0 /dev/sda" really be the answer to everything?
