  • ed8b0de5a   efi: Make efivarfs entries immutable by default ... Browse Code »

    "rm -rf" is bricking some peoples' laptops because of variables being
    used to store non-reinitializable firmware driver data that's required
    to POST the hardware.

    These are 100% bugs, and they need to be fixed, but in the mean time it
    shouldn't be easy to *accidentally* brick machines.

    We have to have delete working, and picking which variables do and don't
    work for deletion is quite intractable, so instead make everything
    immutable by default (except for a whitelist), and make tools that
    aren't quite so broad-spectrum unset the immutable flag.
