I dont see how you plan on implement this if not//with either a 
secondary program loader which stores an redundant environment ////or an 
kernel support that does the similar/same thing I mean you need to have 
a watchdog support,boot counter  which get's cleared when system decides 
it's up and stable,boot limit which tells it how many times it should 
try with an given entry, an entry which points to which 
kernel/image/snapshot to use right?

I'm pretty sure Kay and Lennart must have thought things through so they 
just dont add just some half ass, none future proof, working solution 
that give administrators and embedded distribution fake notion of 
redundancy or a "fail-safe" when images and or kernel or the OS itself 
get's update/upgraded.

If this cannot or will not be reliably implemented there is no point in 
implementing this in the first place from my pov.
