Seems like this distro is getting a lot of traction recently. Has anyone tried it? Is it any good?
Is it a big learning curve? Is this the emacs equivalent of OS configuration/installation?
edit: another question - Could I play around with it by installing in qemu and if I like that, take my configuration.nix from qemu and install it as my main OS?
I’d say it’s a pretty steep curve unfortunately, and nixOS is also not perfect,
mind you
The nix language (that is used for the configuration) itself has sometimes
weird syntax. It’s also a proper functional programming languages with all
bells ans whistles that brings
The documentation is less than ideal (to put it mildley). Most of the times
you need to search reddit (rip) and the forums to find how to do certain
things.
Nix is not FHS
compliant. Basically everything is a symlink to some file in the nix store,
located in /nix. Packages installed with nix are patched to work that way,
but things not installed with it might not run out of the box
As for trying it out, yeah copying the config from the vm should work (except
for maybe some hardware-specific stuff). remember to backup your stuff just in
case lol

It’s really not. It has no runtime for starters; it’s a pure expression language. It can’t i.e. read stdin, open a socket or do an arbitrary syscall.
The end result is always data. You could and can turn every sensible evaluation of Nix into JSON.
There are indeed side-effects but they’re indirect; implied by the data that is the actual end result of an evaluation of Nix expressions. If your expression evals to a derivation (data), Nix will create a .drv file for you for example. They’re well defined and not arbitrary though.

Absolutely. That’s how I got started ;)
If you install Nix (the package manager) on your current system, you can actually directly build a vm from a config file via
nixos-rebuild build-vm.
