GNU Guix vs MX Linux

A method which works across languages and provides a reproducible programming environment.

Guix creates new profile generations for each operation. If anything goes wrong, a simple --roll-back gets you immediately back to the previous, working, generation. Because it is a purely functional package management system, generations don't affect each other, so you're back to the exact same state as before : still working.

Guix pack creates packages which do not need Guix to be run.

Guix is a purely functional package management system. This means that the act of building a package does not have side effects, such as destructively updating or deleting files that may be used by other packages.

See guix pack --help and here.

The clean and declarative syntax makes it easy to define new packages by using an existing one as an example.

Normal users can install packages on a Guix-enabled system, or even run their own Guix instance if the system isn't Guix-enabled.

Can create your own ISO (snapshot) and use it either as live-session and install back when needed.

With the (pre-installed) Snapshot tool you can easily create an ISO of your running system and then save it to a USB (or other media) and use "your own" distro as a live session or install back whenever you like (even on a different PC with different specs with no issues). You can even give that customized ISO to friends (selecting "non-personal" ISO when creating the snapshot; thus resetting the accounts & passwords and Home folder etc.).

Also you can save that ISO directly encrypted via MX Live USB Maker tool. Again, you can install MX encrypted during installation with just ticking a box, no matter if it's the official ISO or your snapshot.

MX Linux comes with its own set of tools called MX Tools, designed to make life easier for users.

It is based on Debian and not based on Ubuntu.

It has almost all tools to repair non booting systems or recover files & folders and save them on a safe place. And when thought together with it starts quick on live-session. In addition, you can do these with "your own", customized distro (snapshot).

After Puppy Linux (which's aimed to run from RAM and which is smaller in size) the second fastest (head & shoulders) booting one (together with the sister project antiX) and also has the option "toram" to run from RAM. Yes, not only when compared to full distros, even far faster than small sized or tiny distros, especially when booted to "live-session", about 2 - 2.5 times faster on an old single core laptop.
