The "user-otp" and "factory-otp" compatible string just depicts a

In hindsight it looks like we are mixing 2 different purposes of 'which 
instance is this' and 'what is this'. 'compatible' is supposed to be the 
latter.

Maybe there's a better way to handle user/factory? There's a similar 
need with partitions for A/B or factory/update.
