That's a completely different thing, though - even though the difference
is rather subtle.
You can remove pretty much any empty directory (if the filesystem
permits it - some don't). HOWEVER, you can not use "." as the final
component of your pathname.
It has nothing to do with home directory: you can try just doing
mkdir /tmp/hello
rmdir /tmp/hello/.
and you'll get the same error (and it _should_ return EINVAL, not EBUSY.
EBUSY is for the "this filesystem doesn't allow you to remove a
directory that is in use" case).
