guix pack on Linux kernel

guix pack on Linux kernel

[Andy Tai]

question the Guix documentation says a bundle created  from guix pack
can run on machines running the Linux kernel.  Does this mean such a
bundle can possibly run on Linux kernel with any C library, or just
GNU/Linux? (providing no other blocking factors, such as the hardware
or driver needed is present; thus I ignore for example lack of X
Windows for graphics programs, etc.)

(of course the most common such machine would be Android devices)

reference to the said GUix document page:

https://guix.gnu.org/blog/2017/creating-bundles-with-guix-pack/

"because Guix captures the complete dependency graph of packages, the
tarball contains everything that’s needed to run <program bundled> and
is going to work in exactly the same way on any system that runs the
kernel Linux!"

The pack includes the C library, so the host C library does not 
matter.

sorry for the series of questions, but a follow on question:

If I create and distribute such a guix pack bundle, is there an easy
way to create a tar.gz file containing the sources to fit GPL
requirements?  I assume now there is no guix command to create a
"source pack" for a guix pack.   Even if there is, can a tar.gz of the
directories of the sources be enough to re-create the binary pack?
Or basically the user shall have the full guix git repo built locally,
plus the sources of the programs bundled, before he or she can
re-create the guix pack.

Question is essentially how to meet GPL requirements (user given the
sources to be able to recreate the binaries distributed from these
sources) for a guix pack.  Thanks

You can get the source with “guix build --source” but indeed I do not
know how to get from the CLI an archive containing all the sources.
However, the API provides all the tools to write a script for “guix
repl”. :-)

All the best,
