go to System / General Configuration and set Webserver Home Page to Apache Default
so that it serves up the content of freedombox.local/var/www/html
Is this the simplest/best way of tackling this?
Frankly, it would be much better if the user websites would also be selectable from the “Webserver Home Page” drop down menu selection.
(But I’d look @sunil 's workaround in Installing and containing custom applications/software - #2 by sunil .)
