[chef] Re: Re: Re: Re: Re: Inserting multiple lines through Chef::Util::FileEdit

["Oleg Volotov" < >]

The methode 'insert_line_if_no_match(...)' calls only the private one 
'search_match(...)' with the right parameters. This methode makes his changes 
only in the variable 'contents'. Try to make a 'f.write_file' after every 
call of 'insert_line_if_no_match(...)'.
