I''m having a problem with variable interpolation that I
haven''t found a good
solution to. I want to use a variable as part of the name of a fact, but
the interpolation doesn''t work as expected. I''ve allowed for
passing the
mac address into my define() but if it''s not provided I want to look it
up
via facter.
if "$macaddress_${name}" {
$final_hwaddr = "$macaddress_${name}"
}
I want Puppet to look up the value of macaddress_eth0 or whatever, but
instead it returns the value of $name. How can I get the appropriate value?

How can I get the appropriate value?Should be a function instead of inline_template: $myvar = "macaddress_${name}" $hwaddr = inline_template("<%= scope.lookupvar(myvar) %>") Nan -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Thanks Nan, until they make a function out of that I''ll keep the template in my cheat sheet.
