You might find them if you continue to search recursively through the
results.

I've set up quite a few chroots for all kinds of services. Experience
says, that guessing (i.e. trying to figure out in advance) will usually
only save you the first few trace-sessions but almost never make the
chrooted service work 100% right away.

As you seem to start having fun with process tracing, try to find out
where resolving fails, or if it is attempted at all.
