Actually I want to apply this to template files so the number for arguments is
know. I do like your idea though. Here is what I did get work work. I don't
like it because it produces warnings. Suggestions welcome.
bundle agent motd_tmp_44(motd_tmp, manager, phone, email) {
vars:
"tmpfile" string => "/var/tmp/cf_templates/motd",
handle => "motd_tmp_44_vars_tmpfile",
comment => "Location of template file on client.";
no_motd_tmp::
"motd_tmp" string => "/var/cfengine/masterfiles/my_motd_tmp";
no_manager::
"manager" string => "John Smith";
no_phone::
"phone" string => "555-555-1234";
no_email::
"email" string => "jsm...@example.com";
classes:
"no_motd_tmp" not => isvariable("motd_tmp");
"no_manager" not => isvariable("manager");
"no_phone" not => isvariable("phone");
"no_email" not => isvariable("email");
files:
"$(tmpfile)"
handle => "motd_tmp_44_files_tmp_cf_templates_motd",
comment => "Copy motd template file",
copy_from => local_cp("$(motd_tmp)");
"/etc/demo_motd"
handle => "motd_tmp_44_files_etc_demo_motd",
comment => "Expand motd file from template",
perms => mog("0644","root","root"),
create => "true",
edit_defaults => empty,
edit_line => expand_template("$(tmpfile)");
}
However, that does create a lot of warnings when it is run:
# cf-agent -IKf ./promises.cf
Scalar variable motd_tmp_44.motd_tmp contains itself (non-convergent):
$(motd_tmp)
Scalar variable motd_tmp_44.manager contains itself (non-convergent): $(manager)
Scalar variable motd_tmp_44.phone contains itself (non-convergent): $(phone)
Scalar variable motd_tmp_44.email contains itself (non-convergent): $(email)
