Are there specific lxc related configuration files needed in a CentOS 
template that my custom image might not have? I'm asking because in 
looking at /usr/share/lxc/templates/lxc-centos I see there are several 
configuration steps that are performed against the installed CentOS 
rootfs, such as disabling selinix, creating a minimal fstab, etc. Most 
of these are already done as part of my image creation process, but I 
see there are other steps I do not include, such as creating 
/etc/init/lxc-sysinit.conf. This is done as part of a specific check for 
CentOS release 6, so I wonder if there is something equivalent needed 
for CentOS 7?
