Good to hear you got it working the way you wanted.
With and without -b do essentially the same thing, just changing where the
results are visible.
With -b:
Combine the set of files in /var/upper with those in /var/lower, with
/var/upper overriding the lower layer,
and make that visible at /var/upper
Without -b:
Combine the set of files in /var/upper with those in /var/lower, with
/var/upper overriding the lower layer,
and make that visible at /var/lower
