Hello!

The pack includes ‘proot-static’, which takes approximately 1 MiB.  The
‘run-in-namespace.c’ wrapper determines its own location via
/proc/self/exe; from there it determines the location of the unpacked
store, and then determines the location of the statically-linked ‘proot’
program.

So it basically automates the PRoot trick described at
<https://guix-hpc.bordeaux.inria.fr/blog/2017/10/using-guix-without-being-root/>.
