Re: Automatic firmware updates?
All are or have been solved. Signed updates? Yup, already done in all serious OS and no need for remote admin capabilities. Even Windows can do that.
Avoid crashing mid-update? Can be done so long as you have enough disk/flash to store the system image twice - create new system in the 'spare' half and finally swap the entry point as an atomic operation, that way you either boot to new or to old, but never to something half-arsed.
Or with less space have a simple boot loader that at least allows recovery from local file and is not updated so low risk of corruption.
