Mike,
that is nice, but have you tried to use delete_lines:: to delete all
unnecessary lines from the file? I think that this might work instead of md5
sum check.
vars:
any::
"to_keep_list" slist => { "#", "@(kernel_tunables)" };
delete_lines:
any::
".*"
comment => "Dont' delete needed sysctl variables or commented lines.",
delete_select => if_doesnt_start_with("@(to_keep_list)");
with
body delete_select if_doesnt_start_with(list) {
delete_if_not_startwith_from_list => { @(list) };
}
