Even under POSIX, "guarantees" and "crash/power failure" do not mesh well. This has been under dispute recently, for example: http://thread.gmane.org/gmane.comp.standards.posix.austin.general/7456/focus=7487 The best we can achieve with POSIX alone is "to make bad consequences less likely". Jonathan already mentioned the knob that allows you to trade performance for more safety. -- Hannes -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
