I'm new to seL4 (and L4 generally).  I'd like to initially run my application functionality in Linux on top of seL4 (x86) and then over time migrate pieces of its functionality to run directly on seL4 to achieve finer-grained confinement. 

I'm having trouble finding any instructions on how to run a Linux environment on top of seL4.  Either paravirtualized or hardware virtualized would be ok.  So far I found pointers to L4Linux but it appears to need L4Re.  Can anyone point me in the right direction?

Thanks,
Rob
