I have from time to time a need of random password without
wanting to write them down (one example is mailman list creation,
that requires a password to be given to be sent to the list owner).
But using /dev/null do not return null, but the empty string, which
doesn't generate a password at all and so do not achieve my use case.
* Fix regression in jinja2 include search path
Since commit 3c39bb5, the 'ansible_search_path' variable is used to set
jinja2's search path for {% include %} directives. However, this path is
the the proper one because our templates live in 'templates' subdirs in
our search path.
This is a regression because previously, our include search path would
include the dirname of the currently interpreted file, which worked most
of the time.

files.
