Fedora 23 netinstall URL
Not sure why I found this so challenging, maybe because I haven't done a netinstall in ages. Anyway, finally figured out how to setup the Installation Source your selected mirror/path/to/installation/end with os/ So for me it was: http://fedora.mirrors.tds.net/fedora/releases/23/Server/x86_64/os/ Key was to end it with os/.
