I can document this in the next preview I send to the
list. Running gnunet via system service is the correct way to run
it, this way multiple unix users can have their own ego (gnunet
term) etc. You will no longer use gnunet-arm, you just use the
gnunet subsystems directly.

I'm discussing it right now, to figure out if this was fixed
later or if this is still relevant to report, and if it was fixed
later if it can be backported.
