Yes, this subject is a good flamewar catalyst. Crashes are not limited to hardware. With a RAID controller with write-back cache (backed) the 'sync' mounted FS is not costly at all. I don't have it right now, but still won't mount my FSes 'async' (and MTA requires 'sync'). The machine has been in near-crash states before (I accidentally exhausted all physical and swap memory a long while ago). -- Dan
