I need help from apache experts. On my system (gentoo 64bit, apache-2.4.20), running an httpd test gives me

A quick search shows that loading mod_unixd.so will do (and did make httpd run for me). Problem is, can I just update apache.conf to load it when apache version >= 2.4? I don't know if doing that would cause failure for other people because mod_unixd has existed since 2.2 and people have run httpd tests fine so far...
