Everyone has asked if I'm using the -f option. The reason I hadn't
done this is that this is going to give me output from a *lot* of
child processes, where all I really want to see is that the main
process receives one bit of information. I expected to see that
one child process was launched, where what it actually does is
forks an exec, which then launches the process. As such, running
a bog-standard truss won't show you what it's launching. The -f
option must be used to get this information. Sadly, that means
going through loads more output, but it looks like the only way to
do it.
