v2.0.0-rc.0

• New Features
  • Uses nerves_initramfs to support pre-start checks for deciding if a
    firmware should automatically be reverted before the kernel is loaded.
    By default, this checks UBoot variable nerves_fw_validated and if the
    firmware has not been validated, a revert will be triggered. This means
    a user must validate the firmware on first boot via
    Nerves.Runtime.validate_firmware/0 or by writing to UBoot directly
