Description of problem:  On Beta 14 OPSD doc:
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/14-beta/html/director_installation_and_usage/installing-the-undercloud#installing-the-director

Step 4.4.1 step 5 At the very end, the command to view pxe images under /httpboot folder fails. 
-------------------- 

This list will not show the introspection PXE images. The director copies these files to /httpboot.

(undercloud) [stack@director images]$ ls -l /httpboot


--------------------

I suspect this is broken/wrong as I tried this on an infrared deployed system as well as on my BM and all I get is:

[stack@undercloud-0 ~]$ sudo ls -l /httpboot
ls: cannot access /httpboot: No such file or directory

Not sure if this should work or the path isn't correct any way we don't get what the doc suggest. Either we remove this of give a correct path, I'm not sure what's the correct answer.
