Case statements don't work inside of resource definitions. There are
three ways I can think of do what you're doing:
1. Use multiple inline selectors. (Very long and ugly.)
2. Write four different definitions of the NTP service and wrap them
in a case statement (Not as long, but still ugly.)
3. Use if statements to set some variables, then use those in a single
NTP service definition. (Shorter, maybe less ugly.)
Here's an example of number 3:
case $lsbdistcodename {
"sarge": {
$ntp = "ntp-server"
}
default: {
$ntp = "ntp"
}
}
if ($virtual == "physical") or ($virtual == "xen0") {
$ntp_enable = "true"
$ntp_ensure = "running"
}
if ($virtual == "xenu") or ($virtual == "openvz") {
$ntp_enable = "false"
$ntp_ensure = "stopped"
}
service { $ntp:
ensure => $ntp_ensure,
enable => $ntp_enable,
pattern => "ntpd"
}
This isn't great, but if you have multiple services that differ in a
similar fashion, you can define all the variables you need in a few
statements at the top of your class and have one short definition for
each service.
