Please ensure that /etc/mtab is a proper symlink. systemd will warn you during boot if /usr is on a different file system than /. While in systemd itself very little will break if /usr is on a seperate partition many of its dependencies very likely will break sooner or later in one form or another. For example udev rules tend to refer to binaries in /usr, binaries that link to libraries in /usr or binaries that refer to data files in /usr. Since these breakages are not always directly visible systemd will warn about this, since this kind of file system setup is not really supported anymore by the basic set of Linux OS components.
