the folder is on each host machine. The folder may already be there for a
different set of builds, so just having the folder there does not mean the
files have been downloaded.
this script will end up being run locally on each system. It will
essentially be on a bunch of test boxes, that people will use the script to
switch between build environments.
I have seen when download task is in there and there is no network
connection the script errors out. I am hoping to avoid that.
My overall intention was to have an ansible script that runs locally that
grabs a list of rpms from a file, checks if the files are in the local
directory, if the files are not in the local directory downloads them, then
installs the builds from a local directory. Normally the system will not be
on a network that can reach repositories. It will only be on that network
if they need to download.
