I made changes on the /etc/environment file and want the webserver user www-data to benefit from them without rebooting the server.
It seems that, in order to reload the /etc/environment file, I only need to login¹.
Therefore, I'm trying to make the www-data user proceed to the login, but didn't find anything relevant.
I'm using lighttpd webserver.
How can I make the webserver (and it's user) aware of the changes in /etc/environment without a reboot?
