This does seem odd. Might I also point out...
To boot a system, enough must be present on the root partition to mount other
filesystems. This includes utilities, configuration, boot loader information,
and other essential start-up data. /usr, /opt, and /var are designed such that
they may be located on other partitions or filesystems.
/usr is the second major section of the filesystem. /usr is shareable, read-
only data. That means that /usr should be shareable between various FHS-
compliant hosts and must not be written to.

currently have a separate /usr, I predict quite a few bug reports because of
