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)
