What do you want? an on-the-fly OTA disabler.
A FAT based file check solution already exists. DISABLE_OTA on the /mnt/us IIRC with a tiny patch to the OTA code.
caveats: Certainly Amazon will check this underlying code file for integrity at point of update so it WILL
require rollback for a non-erroring update.
Which is a pain. That is the reason I vote we won't be including this. Messy.
Ah it's here
