It will have next to nothing. A "stock" install of apache will usually
start from the script /etc/init.d/httpd on Fedora systems. You could
edit that file and insert this command:

  env | sort

which will dump the current environment when the script runs. That will
be illuminating during boot. If you start things from a root login shell,
it will start with root's environment (and that will come via root's
login shell startup).

It is also possible to configure environment values inside Apache's
config files as I recall.
