This approach would hit all systems that install a newly issued BIOS after 2010, which could cause a change in behaviour for such systems. I don't know how to get a "system manufactured" date or "system first powered on" date generically (IIRC these might be exposed in vendor-specific fields on Dell systems). I'm not opposed, but it could result in a change of behavior for still-maintained (as evidenced by newly issued BIOSes) systems. -- Matt Domsch Technology Strategist Dell | Office of the CTO -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
