overriding essential-services

[Ricardo Wurmus]

Hi Guix,

I want to make sure that /etc/environment includes GUILE_LOAD_PATH and
GUILE_LOAD_COMPILED_PATH, because that’s needed for offloading.
“/etc/environment” is created by the “session-environment-service”
service, which is part of “essential-services”.  It is not part of
%base-services, so I cannot catch it with “modify-services” and extend
it.

How would I go about extending it?

For now I’ll use ~/.ssh/environment and “PermitUserEnvironment=yes”, but
I think it would anyway be good to have a mechanism to easily change the
contents of /etc/environment.
