Environment variables to always set at login.
</para><para>
Note, these variables may be set in any order so no session
variable may have a runtime dependency on another session
variable. In particular code like
<programlisting>
home.sessionVariables = {
FOO = "Hello";
BAR = "$FOO World!";
};
</programlisting>
may not work as expected. If you need to reference another
session variable, then do so inside Nix instead. The above
example then becomes
<programlisting>
home.sessionVariables = {
FOO = "Hello";
BAR = "''${config.home.sessionVariables.FOO} World!";
};
</programlisting>
'';
};
