The real issue is that you cannot put /usr on a dedicated partition anymore as of CentOS 7. This is because /bin, /lib and /lib64 are symbolic linked in the /usr equivalents now. The (previous) purposes of having a separate /bin and /lib was so that programs and libs required at boot time could be run before the rest of the fs was mounted up if /usr were on a separate partition. Now they've been consolidated and symlinked so if you put /usr on a separate partition then the system won't be able to access critical apps during boot.
_but_, you can/could have a minimal /usr with required files for boot. then after the mounting, usr partition lays in.
You can thank Fedora for making that rather pointless change and breaking that capability.
there are a lot of 'thank yous' for fedora project. 1 of which made 3 of my drive lvm when they were ext4. :-\
