Title is quite self-explanatory, reason I wonder is because every now and then I think to myself “maybe distro X is good, maybe I should try it at some point”, but then I think a bit more and realise it kind of doesn’t make a difference - the only thing I feel kinda matters is rolling vs non-rolling release patterns.
My guiding principles when choosing distro are that I run arch on my desktop because it’s what I’m used to (and AUR is nice to have), and Debian on servers because some people said it’s good and I the non-rolling release gives me peace of mind that I don’t have to update very often. But I could switch both of these out and I really don’t think it would make a difference at all.
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?
Your personal files e.g. ~/Documents are not recreated, you’ll still need backups of those.
caveats are you’ve got to use:
But all this can be written in the one flake, so yes
nixos-install --flake <GIT URL>#<HOSTNAME>Is sufficient for me to rebuild my desktop, laptop or server from the same repository.I’ve never used Gentoo, and I’m sure there are other methods of achieving the same level of reproducibility but I don’t know what they are.
Nixos can be as modifiable as Gentoo with the caveat being it’s a massive pain in the ass to do some things. I have a flake for making aarch64-musl systems which has been an endeavour, and… It works? I have a running system that works on 2 different SoCs. I do have to compile everything quite often though.
There are efforts to recreate Nixos without systemd, but that’s a huge effort; because it’s very “infrastructure as code”, you have to change a lot of code where editing a build script would’ve sufficed on arch/Gentoo.
As for nix vs guix, guix was described to me as “if you only ever want to write in scheme”, whereas nix feels much more like a means to an end with practical compromises spattered throughout.
