Instead of 'default saved' being an option, or having an option to set the  
default to a specific entry, the option to toggle the savedefault command 
on the default NixOs should allow all desired behavior.

IRC ports are blocked here, so I can't join #nixos without tunneling 
through something else.

Hmm, that probably covers most, if not all of what the grub's fallback 
thing does.

This suggestion might just be complicating the boot process, making nixos 
not boot by default. For my use case, it might just be easier to call the 
nixos grub from another os's grub.
