Hi Christian,

Thanks for your kindly help, and i have had a quick look about the L4Re ducument!
In your explanation, L4Re cosists of a bunch of services. So it just provides basic services for L4Linux, but not a enviroment for normal application!
I describe my thought about L4 related stuff as below.
For normal user, they can only use L4Linux or Karma VM, which provides a Linux enviroment. They can not use the L4Re as a enviroment because no Linux env?
But for L4 developer, how can they build application derectly on microkernel? Just depend on the systemcall provided by microkernel and/or have some dependence on those existing service from L4Re?

Best,
Chen
