NixOS have this feature called specialisation which is used for some minor/major alterations to ur OS config at boot entry. So that u don't have to dual boot 2 #Linux OS for different purposes. Eg: One for normal use, one for gaming/whatever purpose
The customisation difference could be changing from apps to even kernels if u wish.
The most awesome thing is it won't take extra storage like running 2 os. It only takes extra space for the extra config/apps u add.
