If you want to copy certain files from the hub onto the same location on the clients, you can do something like this:
vars:
"files" slist => { "/some/file", "/other/file", "/one/more/file" };
files:
"$(files)"
copy_from => secure_cp("$(files)", "$(sys.policy_hub)");
This will loop over the files, copying each one in turn. Make sure you include the appropriate standard library file to secure_cp(), something like this:
body common control
{
inputs => { "lib/3.5/files.cf" };
bundlesequence => { ... };
}
