Interesting. So XFS is not only a Bad Idea for /, but also for anything
that might enter S3/S4. Not nice. I sure hope it doesn't do a
half-assed job of flushing and checkpointing itself during machine
shutdown/restart like it apparently does when told to "sync" before
S3/S4...

Would you be so kind to disclose to us, the uninitated, which other
filesystems are unsafe when faced with a sleep/suspend request?
