Hi Soham,

I think as a hack, you can reconfigure your system once per kernel and
then you will be able to select which one you want to load at boot by
selecting the right generation in the grub menu.

I think its possible to get something a bit cleaner like what nixos
have, but you’d need to code it yourself :)

Have a nice day,
Noé
