process and "parent" process is more conducive to policy generation.
Previously, tracing of a given program worked something like this:
fork()
if (child)
execprogram()
else
dotracing()
That means that if you "systrace -a named", named would fork and
background itself, but you would never get your prompt back because
systrace didn't exit. Now it works like this:
fork()
if (interactive)
if (child)
execprogram()
else
dotracing()
else
if (parent)
execprogram()
else
fork()
if (parent)
exit(0)
setsid()
dotracing()
This makes it *much* easier to do automated policy generation for
tasks run from rc.d. Or, for that matter, makes it much easier to use
systrace with tasks run from rc.d.
