this sort of goes against the grain of what puppet intends but this is what I
do for a few things... (watch out for mail driven line wrapping)
class mod_puppet::deployment_files {
exec{ "Make /etc/puppet/deployment_files":
command => "/bin/mkdir /etc/puppet/deployment_files",
unless => "/bin/ls -l /etc/puppet/deployment_files",
}
}
class postfix::configure {
include mod_puppet::deployment_files
file{"/etc/puppet/deployment_files/postfix-main.cf":
ensure => present,
owner => postfix,
group => postfix,
mode => 0664,
content => template("postfix/main.cf.erb"),
require => Class["postfix::install", "mod_puppet::deployment_files"],
notify => Class["postfix::service"],
}
exec{"Deploy postfix/main.cf from template":
command => "/bin/cp /etc/postfix/main.cf /etc/postfix/main.cf-backup;
/bin/cat /etc/puppet/deployment_files/postfix-main.cf > /etc/postfix/main.cf;
/bin/touch /etc/puppet/deployment_files/postfix-main.cf-deployed",
unless => "/bin/ls -l
/etc/puppet/deployment_files/postfix-main.cf-deployed",
require => File["/etc/puppet/deployment_files/postfix-main.cf"] ,
}
}
