You could use an "exec" resource which is subscribed to a file and has
"refreshonly => true", like:
class reboot ($reason = undef) {
file { 'reboot_trigger':
path => '/.reboot',
ensure => present,
content => "${reason}",
}
exec { 'reboot':
command => "/sbin/shutdown -r now",
subscribe => File['reboot_trigger'],
refreshonly => true,
}
}
Your agents will now reboot whenever you change $reason.
