The php programs in /var/www/html will be chowned to the user "webapps" for new installs, or when the sh script for updates for that program is run. This is so that suPhp won't choke on the root owned files. This also means that we need to make sure no other user uses that name, so it's now declared as reserved. If you have a user account named webapps, it will need to be renamed. You can use the script: /usr/local/directadmin/scripts/change_username.sh to do so.
