yes, definitely. The only requirements we have on Linux are a 64-bit processor with a kernel greater than 2.6.32. I'd love to see an example in our docs on this, I'll make a note for the team.
You should be able to extract a hart file w/ the
hab executable to
/hab or some other directory with correctly patched glibc etc. See  for more info on how this works under the hood.
The export commands exist because Docker + Mesos have specific packaging requirements. The source for
hab dockerize is a great place to start if you're curious , and it's quite short and to the point.
