Howdy,
Somehow I had never tried edit_backup => "rotate" before (I always used
"timestamp"), and maybe I'm being dense, but I don't think it's working
properly. Here is a self-contained sample policy:
body common control
{
bundlesequence => { "editexample" };
inputs => { "cfengine_stdlib.cf" };
}
bundle agent editexample
{
files:
"c:/cygwin/etc/motd"
edit_line => insert_lines("Unauthorized use will be prosecuted"),
edit_defaults => rotate;
}
body edit_defaults rotate
{
empty_file_before_editing => "false";
edit_backup => "rotate";
rotate => "4";
max_file_size => "300000";
}
Now, when I run it:
$ cat /etc/motd
Welcome to the system.
$ ls /etc/motd*
/etc/motd
$ cf-agent.exe -KI -f ./fileedit_example.cf
-> Edited file c:/cygwin/etc/motd
$ cat /etc/motd
Welcome to the system.
Unauthorized use will be prosecuted
$ ls /etc/motd*
/etc/motd /etc/motd.cf-before-edit
$ sed -i -e 's/prosecuted/frowned upon/' /etc/motd
$ cat /etc/motd
Welcome to the system.
Unauthorized use will be frowned upon
$ cf-agent.exe -KI -f ./fileedit_example.cf
-> Edited file c:/cygwin/etc/motd
$ ls /etc/motd
/etc/motd /etc/motd.cf-before-edit
$ cat /etc/motd
Welcome to the system.
Unauthorized use will be frowned upon
Unauthorized use will be prosecuted
$ cat /etc/motd.cf-before-edit
Welcome to the system.
Unauthorized use will be frowned upon
As you can see, the behavior doesn't change from the default - it is just
making one backup copy of the file, without rotation.
Am I doing something wrong, or is this broken? I'm using Nova 2.0 on Windows.
