 "call dumpsys", OK, I have made a note of that.

 small root ffs on wd0a.  large cgd on wd0e.  ffs inside the cgd is
 mounted on "/cgd1a".  several nullfs mounts make several top level
 directories inside the cgd appear like top level directories inside
 the root (e.g. for dir in home usr var blah blah; do mount -t null
 /cgd1a/${dir} /${dir}; done).
