Here is my simple translator named logrelay.
A first attempt to syslog the proc server could be the following:

The above modifications won't produce something visible unless an
error has occured. If you want to see some meaningless action :)
you can do this which creates a log entry every time a new process
is created:

What do you think of all this? Can they actually be used on Hurd
or am i wasting my time? (nothing wrong with the latter :) )
Any feedback is good feedback.
