Comment # 1 on bug 1194739 from Stefan Dirsch

803 MB and 442 MB doesn't sound that much to me.

I already have

# cat _constraints 
<constraints>
  <overwrite>
    <conditions>
      <arch>ppc</arch>
      <arch>ppc64</arch>
      <arch>ppc64le</arch>
      <arch>x86_64</arch>
      <arch>i586</arch>
    </conditions>
    <hardware>
      <disk>
        <size unit="G">7</size>
      </disk>
    </hardware>
  </overwrite>
</constraints>

Is there also something for the minium amount of RAM? Any experience wit that?
Anyone using this already successfully?
