I'm not sure what this really means but it looks rather important to me, if 
it is not being allowed to be installed. before a fresh install of Void, 
and even after a Fresh update using xbps-install -Su
if it is having so many conflics maybe it nees to be looked at -- just 
bringing it to your attention... JIC 

[root@void ~]# xbps-install -Su  base-system-busybox
