I can very well accept that argument. What I am trying to do is only make _someone_ writing a fs listen to the problem, and maybe - only maybe - in _his_ fs it is not as complicated and so he simply hacks it in. I am only arguing for having a choice. Not more. If e.g. reiserfs had the feature I could simply shoot all extX stuff and use my preferred fs all the time. That's just about it. No religion involved. I am not arguing this type of feature as a _must-have_. I only think regarding the neat stuff that is already inside reiser (just to name my currently preferred fs) it would be very kind to have write-error-recovery additionally. Regards, Stephan
