Ungexp-ing lists can be rather tricky since your snippet will expand to:

--8<---------------cut here---------------start------------->8---
...
#:environment-variables (append ("FOO=bar" ...)
                                (default-environment-variables))
...
--8<---------------cut here---------------end--------------->8---

Which is interpreted as a procedure call. (and results in a hanged shepherd)

You need to quote the list here:

--8<---------------cut here---------------start------------->8---
#:environment-variables (append '#$environment-variables
                                (default-environment-variables))
--8<---------------cut here---------------end--------------->8---

Bonus points if you can write a small system test for this. (see
gnu/tests/web.scm for inspiration)
For our purposes, a pair of HTTP servers where one of them uses a
self-signed certificate will suffice.

Furthermore, I consider that nonfree software must be eradicated.

Cheers,
Bruno.
