Yeah, was trying originally to work out how to apply that. I don't know
whether this is the prettiest, but it works:
define append_aliases($other_aliases) {
$host_aliases += $other_aliases
host {
"$name.aao.gov.au":
ensure => $ensure,
ip => $ip,
host_aliases => $host_aliases,
}
}
define hostentry($ip, $hostaliases = [], $ensure = present) {
host {
$name:
ensure => absent,
}
$host_aliases = [ $name ]
append_aliases {
$name:
other_aliases => $hostaliases,
}
}
My original struggle was in working out how to initialise $host_aliases
in the caller to just $name, then appending the rest of the aliases.
Doing it the other way around was easy - I was just struggling with the
syntax and scoping. I would have liked to be able to reuse the parameter
name $host_aliases, but far too much juggling to get it around in the
right order to have host_aliases appended back onto something that ends up
being called host_aliases again.
