On v2 of my website I wrote a post on configuring a webserver for testing/developing purposes. In that post I explained how to adjust the umask of Apache. I did that by changing the Apache startup script. But, of course, when apache is updated/upgraded, you custom mod will dissapear. In coincidence I stumbled upon a post that explained how to add environment variables to apache without modding the distribution scripts.
All you do is adding the desired variables to “/etc/apache2/envars”. That’s it!
