Well, there are variables like $fqdn, $hostname, $environment,
or you can add your own.
I use a definition roughly like this:
define my_file (ensure = "file", $user, $group, $mode,
$source_prefix)
{
file { $name:
ensure => $ensure,
user => $user,
group => $group,
mode => $mode,
source => [
"${source_prefix}.$fqdn",
"${source_prefix}.$hostname",
"${source_prefix}.$environment",
"${source_prefix}.BASE",
],
}
Usage is like this:
my_file { "/etc/resolv.conf":
user => root, group => root, mode => 0644,
source_prefix => "puppet:///modules/my_module/resolv.conf",
}
You can easily adapt this to use a different list of sources. With more
trouble, you can generate the list of sources at run time depending on
some other conditions (and I actually do that).

No, but you can define your own variable and use that, or you can wrap
it in a definition and use $name inside the definition.

No. You need to specify each level explicitly. See issue #86
<http://projects.puppetlabs.com/issues/86> for discussion of how such a
new feature might eventually work.
