I would imagine that this would vary based on your sysvinit implementation.

With OpenRC you can set variables per-service in /etc/conf.d, and I
imagine that systemd would offer something similar within its unit
files.

I believe that anything set in /etc/env.d/ will affect services as
well as interactive shells under OpenRC.  Considering my apache
process appears to have picked up an XSESSION from there that seems
likely.

init does whatever it wants to do.  Anything inherited by a process
was set by init or one of the children between it and the process of
interest.  Distros tend to vary a fair bit in terms of their preferred
way of accomplishing this.
