I need to see how -p will affect on directives that use conf prefix
such as "include", "ssl_certficate*", and "auth_basic_user_file".
Historically, nginx had the single prefix (not conf one), but this was
uncomfortably for Linux packages, where now the conf prefix is /etc/nginx,
while default prefix is somewhere in other place.
