[CentOS] Can't delete or move /home on 7.3 install

Tried this in both AWS and GCE as I though it may be a specific cloud
vendor issue. SELinux is disabled, lsof | grep home shows nothing,
lsattr /home shows nothing. Simply get "Device or resource busy."

Works just find on 7.2 so I'm kinda at a loss. Scanned over the RHEL
release notes and didn't see anything. Anyone else have this issue? We
move our /home to another mount point and symlink /home to it ..
