That still didn't work. It must not be reading that httpd.service file.

-bash-4.3$ umask
0022

The problem is then when the apache user, through the joomla admin
front-end, needs to make changes (upload new module, etc) and the
group doesn't have write privileges.

I could sgid the directory, or write a cron script that changes all
the permissions back as one user suggested (horrible idea), but making
all the files and directories group-writable for user apache is a bad
idea if the apache daemon (or joomla running as the apache user) gets
compromised, resulting in a shell. This is the problem I'm trying to
avoid.

Thanks,
Alex
