Alright. Lets first keep all options. At another point in time we can
rethink the default options. Maybe when implementing configuration for
auditd.

Hm, it seems that 'gnu/services.scm: (activation-script)' ensures the
existence of /var/log before the auditd activation gexp is running. So,
the reasoning behind your remark is that we can not guarantee the
existence of /var/log in every case? What cases might that be? I will
take care of it anyway for the sake of robustness, but i am curious.

I was under the impression that every activation script is run it its
own process. But that is not the case. This changes things, more care
is needed.

Patch will follow later.
