<title>Proxy Environment Variables</title>
<para>The Nix installer has special handling for these proxy-related
environment variables:
<varname>http_proxy</varname>, <varname>https_proxy</varname>,
<varname>ftp_proxy</varname>, <varname>no_proxy</varname>,
<varname>HTTP_PROXY</varname>, <varname>HTTPS_PROXY</varname>,
<varname>FTP_PROXY</varname>, <varname>NO_PROXY</varname>.
</para>
<para>If any of these variables are set when running the Nix installer,
then the installer will create an override file at
<filename>/etc/systemd/system/nix-daemon.service.d/override.conf</filename>
so <command>nix-daemon</command> will use them.
