What do you mean by once? It's slow? Or some other reason?
I need to get the first item, then the second, and if the second is not
there pass the first.
(ip_list is a custom fact that lists the machines ip addresses sorted,
except 127.0.0.1)
:-?
I think it might be better for my case to define the custom facts as
iplist_1, iplist_2. But I'm not sure what are the downsides of using
inline_template, if there are next to none I think I'll use it.
Thank you for the quick reply and info. :)
