cfengine 2.0.3 - do I misunderstand typecheck or is it a bug?

[Joe Ramey]

I am using cfengine version 2.0.3.

I have a simple cfengine.conf file:

------------------------------------------------------------------------------
control:

  actionsequence = (
                     copy
                    )

copy:

    /etc/ar.master dest=/etc/ar mode=0444 owner=root group=root type=checksum 
typecheck=true

------------------------------------------------------------------------------

Suppose /etc/ar is currently a symlink:

$ ls -l /etc/ar*
lrwxrwxrwx   1 root     other          7 Jul 10 17:50 /etc/ar -> ar.real
-r--r--r--   1 root     other        129 Jul  9 18:53 /etc/ar.master
-r--r--r--   1 root     other        129 Jul  9 17:57 /etc/ar.real
$ 

When I run cfagent on the cf file above I would expect it to do
nothing since /etc/ar.master and /etc/ar are not the same type, and
typecheck=true.  However, it goes ahead and performs the copy:

$ cfagent --file cfengine-debug.conf
$ ls -l /etc/ar*
-r--r--r--   1 root     root         129 Jul 10 17:53 /etc/ar
-r--r--r--   1 root     other        129 Jul  9 18:53 /etc/ar.master
-r--r--r--   1 root     other        129 Jul  9 17:57 /etc/ar.real
$

I would have expected it to perform the copy (after first
removing the symlink) only if typecheck=false.
