[poky] install and kernel directories in rootfs tarball

[Enric Balletbò i Serra]

Hi,

After building a recent sato image using latest commits from git
repositories, the rootfs contains current directories

  $ ls
  bin  boot  dev  etc  home  install  kernel  lib  media  mnt  proc
sbin  sys  tmp  usr  var

Are the 'install' and 'kernel' included in rootfs for some reason or
it's a bug ?

Cheers,
   Enric
