unfortunately, tests are executed virtualized with lxc/lxd, while
technically it seems to be possible to execute them, but it will 
require
fixing (but probably rewriting) python test runner code. Possible 
but
not feasible i think.

On the other hand, as far as it is mentioned in their release 
process,
sources release tarball is releaced after tests passing.

;; tests are virtualized with lxc/lxd, it is not very feasible
;; to make them executable under guix build

Will this commend do the work?
