Hello,
I've suggested some small changes which I've attached as patches. I also 
have some questions and comments:

How will you serialize g-expressions? It seems that they are to be added 
to the store as scripts with 'program-file', but I can't figure out how 
to extract the file path from the resulting object; I tried in a REPL, 
program-file objects cannot be used as strings like this function seems 
to suggest, and none of the their properties seem to clearly give their 
location in the store.

Also, how are you testing your work? I asked in the IRC channel and they 
suggested spooling up a VM via 'guix system vm' with an operating-system 
definition containing the experimental service, but perhaps you have 
your own method.
