fakesystemd owns same directories systemd does and has set provides to 
fulfill most RPM dependencies for systemd. For example you want to run 
httpd in your Docker container which brings systemd, devicemapper, 
kmod... in. If the base image contains fakesystemd none of these 
dependencies is installed. If you really need systemd in you container 
you can use following command:

yum swap -- remove fakesystemd -- install systemd systemd-libs

systemd-container (I think it's the same thing you refer to as "mini") 
should remove dependencies which does not make sense in container (again 
devicemapper, kmod...) and hwdb and should run as init in multi-service 
containers. Well I am not sure if it ends up being really 
"systemd-container" or simply "fixed" systemd. If I am not mistaken this 
was second topic for last Base WG meeting which we didn't get to:) So 
hopefully this week?
