Apache is 2.4.7 in the new 14.04 release.
Various website and release notes mention that lua via mod_lua became available.
There is a lua.load file in /etc/apache2/mods-available, but the corresponding module, mod_lua.so is not present in /usr/lib/apache2/modules.
There is not libapache2-mod-lua to be found in apt.
My question is: how is mod_lua installed?
