From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

So I think Guix (and Nix) is the most technologically advanced package manager in existence, and I hope someday all package managers work like Guix.
One other very interesting feature about Guix ~~(which I don't think Nix is doing yet)~~ (which Nix also does) is that they have implemented a fully verifiable bootstrap, meaning every step of building the kernel, including the steps taken to build the C compiler toolchain, are produced by code that is simple enough for a group of humans to check for correctness and safety. Also, every step of the build process exists in the package repository, with no reliance on externally built binaries for anything, not even the C compiler toolchain. They accomplish this with a multi-phase bootstrap process, where a smaller, simpler C compiler is used to build GCC.
Do I use Guix? Well, no. Simply put, it is not quite to the point where it just works on a lot of the computer hardware that I own. With a bit more work, with a few more developers, and a bit more money invested, Guix could pretty soon become as reliable and useful as Debian or Fedora. But it is not quite there yet. And frankly, I have other more important things to do than worry about debugging problems with the operating system I am using.
Full-source bootstrap isn't about just the kernel, it affects every piece of software. With GUIX and Nix, every single package can be fully traced back to the bootstrap seed.
Though it should be noted that you do require a running Linux kernel on an x86 machine in order to bootstrap.
Unless we get some serious money, effort and/or regulation w.r.t. OSS firmware, that will likely never be the case.
That has nothing to do with its technology though, that's a political issue. GUIX is a GNU project and acts like proprietary software does not exist/is not a basic necessity in 2023.
Gross oversimplification, Guix absolutely knows that proprietary software exists, but also Guix is a project that values transparent build process (unlike Nix, which allows binaries and nonfree packages).
If you don't have the requisite bare metal to run Guix by itself, you can run it as a foreign package manager (on top of your existing distribution), in a virtual machine, or alongside package channels outside of guix that package nonfree software.
The linux-libre kernel is only an issue for Guix System (the analogue to NixOS for Nix) and for users who need that specific hardware to be used. Guix is a breath of fresh air in package managers who attempt to sweep nonfree software under the rug and try to make the issue invisible.
That's a bit disingenuous wording as modern hardware that can run without proprietary firmware is an absolute rarity at this point.
The vast majority of people on earth do not have access to such hardware.
Point taken. I was talking about the OS aspect of both though, given that @[email protected] compared it to Debian and Fedora.
The project should have really kept the GuixSD name. Much clearer separation and also sounds a lot better.
Which ones?
In Nix, you get a giant red error when you try to eval unfree software and need to explicitly opt-in.
But it's not impossible, nor is it something that can't be solved in the future with CPU architectures like RISC-V.
Agreed.
I should have been more clear, excluding nonfree blobs were widely decided to be a lost cause across the distribution space. The final being Debian very recently. Tbh I do sometimes wish that Guix took the Nix approach with
hardware-configuration.nix, but the fact remains is that the Guix maintainers do not wish to maintain nonfree packages and I respect that decision as Guix doesn't go out of its way to prevent others from installing the nonfree blobs/packages themselves.Nix is also working on reproducible builds. In fact, the minimal installation CD for NixOS last release was reproducible. https://discourse.nixos.org/t/nixos-reproducible-builds-minimal-installation-iso-successfully-independently-rebuilt/34756/
Another interesting thing about Guix is that it compiles everything itself (with an option to outsource the heavy lifting in case you're on a Raspberry Pi or something). Layers of abstraction not talking to each other properly is a conceptual pet peeve of mine, so I like the idea of everything being visible to the compiler like that.
As far as I understand it, Guix will download pre-built binaries for most packages from a cache by default, and the Guix OS distribution makes sure the x86_64 binaries for the latest package descriptions are always cached, so you should usually not have to locally build packages.
But of course you can easily tweak the default configuration of packages you install and trigger a local re-build of those packages, since changing the configuration of any package causes a cache miss.
