OK. Given that write caching may be required for performance reasons or there might be other possible reasons which would result in preen-unrepairable fs corruption on power loss, my question is now: Is it a really bad idea to run "e2fsck -y" on every boot? I'm not expecting magic: I realise that in such configurations there is risk of data loss. However, every time I have seen preen fail so far, running "e2fsck -y" gets things back into bootable state and I'm simply wondering how much potential trouble I would be getting myself into by automating this.
