Submission + - Galaxies grow by 'Cannibalism'.

Smivs writes: "Scientists studying Andromeda have discovered that galaxies grow by eating each other. An international team of scientists mapping Andromeda discovered stars that they said were "remnants of dwarf galaxies". The astronomers report their findings in the journal Nature. This consumption of stars has been suggested previously, but the team's ultra-deep survey has provided detailed images to show that it took place. This shows the "hierarchical model" of galaxy formation in action. The model predicts that large galaxies should be surrounded by relics of smaller galaxies they have consumed."

That depends on if you are using Xen or Qemmu. There's a design flaw in Xen/SELinux that will allow a hacked guest to write to the physical drive without notifying SELinux. This was "fixed" when the Qemm/SELinux interaction was worked out. There's a blog from one of the Red Hat SELinux guys that gives more detail, but I can't find the link just now.
