I might be wrong on some points here but I *am* sure there is a
difference.
AFAIK, mounting 'sync' means any and all update-operations will go to
disk immediately, and the system call won't return until a write is
done. 'nosync' takes this guarantee away.
The fsync() calls only affect data (on ext2fs) and don't guarantee that
metadata is written. Mounting sync() does.
I hope this makes sense. I need more caffeine.
