[Fedora-livecd-list] Why --bind mount /var/cache/yum?

[Warren Togami]

imgcreate/creator.py:
         # bind mount system directories into _instroot
         for (f, dest) in [("/sys", None), ("/proc", None),
("/dev", None),
                           ("/dev/pts", None),
                           (cachesrc, "/var/cache/yum")]:
             self.__bindmounts.append(BindChrootMount(f, self._instroot, 
dest))

Anyone know why we are --bind mounting /var/cache/yum from the host into 
the chroot during install when we aren't using it?
