Hi Aniket,

In the distros you mention, software is pre-compiled and the .tar packages
have a directory structure that defines where do the packaged files need
to be installed. Those packages don't define how the software has to be
compiled and they don't include the sources.

Guix is not bypassing those systems: Guix is one of those systems. Guix is
a package manager.

The main difference is that Guix describes how is the source compiled and
installed in a recipe. When the user installs a package using:

guix install packagename

The package sources are downloaded, compiled and installed in the system,
following the recipe.

Guix also has ways to keep packages separated to avoid dependency collisions,
ad-hoc environments, time traveling, package installation history with a
reasonable rollback system... and some other interesting features.

Guix is also a software distribution built on top of the Guix package manager
that extends those interesting tools further and defines a uniform way to
describe your operating system.

Hope this helps.

If you have further questions, don't hesitate to ask them.

Regards,
Ekaitz
