Hello Guix!
I've rediscovered the little gem that is (guix services configurations),
and attempted to make it more generally useful by adding an option to
opt out of serialization (which is not well adapted for producing a list
of command line arguments from the configuration for example):

Unfortunately, it doesn't work, at least when using it from 'guix
system'. I've also tried a version relying on syntax-parameter instead
of a parameter, with the same result.
Would someone know how it could be made to work?
Thanks,
Maxim
