Is the restoration method mentioned here really only achievable via nixos? How can you be so confident that you are truly reobtaining an “exact same system”?

Nixos consistently intrigues me because of what it seems to be accomplishing but I can never dive in because there seems to also be many warnings about the investment required and the potential for other more complicated and really nuanced drawbacks to arise.

Give it to me straight–is it offering a new approach of stability with the emphasis on reproducibility? If I’m a gentoo enjoyer hardset in my ways, what could I stand to gain in the nixos/guix realm?

May I ask why the strict yt avoidance? Have no intentions of persuading you either way, just curious.
