Hello,
This is one of my first promises. I am trying to setup apt to use multiverse,
run apt-get update if repaired, and then follow on with installing
ec2-api-tools. It works fine. However, all three steps are always run, even
if the file is already uncommented, apt-get update has already been run. How
do I get cfengine to recognize that the system is already in the desired state?
provisioning_tools is the bundle I am including in my bundlesequence
Ben
bundle agent enable_multiverse
{
files:
"/etc/apt/sources.list"
comment => "Enable mutliverse in apt sources",
edit_line => uncomment_lines_matching(".*deb.*multiverse.*","#"),
classes => if_repaired("sources_list_changed");
commands:
sources_list_changed::
"/usr/bin/apt-get update"
comment => "Update packages with new settings";
}
bundle agent provisioning_tools
{
vars:
"match_package" slist => { "ec2_api_tools" };
packages:
"$(match_package)"
depends_on => { "enable_multiverse" },
package_policy => "add",
package_method => generic,
action => log_repaired("stdout", "Package ${match_package} installed");
}
