[systemd-devel] Linux kernel API

[ScotXW]

Hi,

systemd is written exclusively for the Linux kernel because this offers 
advantages over the POSIX API. To illustrate the difference between 
Linux kernel API and POSIX API I created a diagram, see [1].

On topic: It could be used to illustrate the reasons for this decision.
1. Could you have a look and check whether it is correct?
2. Ideas?

Off topic:
Do you know more programs that are Linux kernel-only?

Thank you,
ScotXW
