[chef] Append text to beginning of file

[Alexander Skwar < >]

Hello

With Chef 11.8.2 and FileEdit and the help of this list :), I've now
got a way to replace text in a file and use the captured text. As it
turned out, I'm not using the captured text at all… Oh, well :)

I am now replacing all old values in a config file (sshd_config, to be
exact). And when a certain config setting wasn't there at all, I
insert a line with the new setting. But it will get appended to the
file; it will be at the end of the file.

That's (maybe…) a problem, as a sshd_config file might have a "Match
…" block at the end.

Is there maybe an easy to way to add text to the BEGINNING of the file? :)

Here (or, for maybe better readability on
http://pastebin.com/1QWfsnFZ) is, what I've got now:

#############################################
# SSH Parameter
{"Protocol" => "2", "LogLevel" => "INFO", "MaxAuthTries" => "4",
"IgnoreRhosts" => "yes", "HostbasedAuthentication" => "no",
"PermitRootLogin" => "no", "PermitEmptyPasswords" => "no", "Banner" =>
"/etc/issue.net"}.each do |param, value|
    cfg_file = "/etc/ssh/sshd_config"

    replace_line_re = /^#{param}.*/
    insert_line_text = replace_line_text = "#{param} #{value}"
    insert_line_re = /^#{replace_line_text}/

    ruby_block "CIS: SSHd Parameter modifizieren. " + param + " => " + value 
do
        block do
            fe = Chef::Util::FileEdit.new(cfg_file)

            # Alte Werte durch neue Werte ersetzen
            fe.search_file_replace_line(replace_line_re, replace_line_text)

            # Zeile mit neuem Wert am Ende der Datei einfügen - falls
nicht schon vorhanden
            fe.insert_line_if_no_match(insert_line_re, insert_line_text)

            # Datei schreiben
            fe.write_file
        end # of block do
        notifies :reload, "service[ssh]", :delayed
    end # of ruby_block "CIS: SSHd Parameter modifizieren. " + param +
" => " + value do
end # of {"Protocol" => "2", "LogLevel" => "INFO", "MaxAuthTries" =>
"4", "IgnoreRhosts" => "yes", "HostbasedAuthentication" => "no",
"PermitRootLogin" => "no", "PermitEmptyPasswords" => "no", "Banner" =>
"/etc/issue.net"}.each do |param, value|




Thanks so much again,
