Hi, I think that I can understand both views, but I can only say that I think the concepts needed to exploit the different execution domains within one process is asking for a new operating system and that I guess this new operating system might be S/390-specific or the applications using it would be specific to S/390, but then the IBM model of having one OS (Linux) for every IBM eServer would not fit for this thing.
>From the development and testing perspecive it would also be better to work on improving the existing Linux applications and operating system environments to run a normal user, use capabilites, compartments (chrooted environments) and everybody, not only the S/390 server users would benefit.(I want to have the same capabilies on my home server or PDA) Bernd
