>Description:
	
	When an object is used as a file in a version but become a directory
	in any later version mergemaster neither remove file nor create the
	new directory so the install target file under that directory fails
	(and mergemaster say "installed successfully").


>How-To-Repeat:
	
	First of all you need to have an "always upgraded installation  :-)",
	than check if you already have /etc/security as a file:

	# ls -land /etc/security
	-r-x------  1 0  0  214 Jan 21 16:22 /etc/security

	If this is your case start a mergemaster (i use -cvsi), at the end
	check log, scrolling back console or xterm, you'd have this lines:

[...]
 *** Temp ./etc/rc.d/sshd and installed are the same, deleting

  *** There is no installed version of ./etc/security/audit_class

install: /etc/security exists but is not a directory
   *** ./etc/security/audit_class installed successfully

  *** There is no installed version of ./etc/security/audit_event

install: /etc/security exists but is not a directory
   *** ./etc/security/audit_event installed successfully

  *** There is no installed version of ./etc/security/audit_control

install: /etc/security exists but is not a directory
   *** ./etc/security/audit_control installed successfully

  *** There is no installed version of ./etc/security/audit_user

install: /etc/security exists but is not a directory
   *** ./etc/security/audit_user installed successfully

  *** There is no installed version of ./etc/security/audit_warn

install: /etc/security exists but is not a directory
   *** ./etc/security/audit_warn installed successfully

 *** Temp ./etc/ssh/ssh_config and installed are the same, deleting
[...]

	You can even simulate this situation:
	# rm -rf /etc/security
	# touch /etc/security

	and than run mergemaster as noted above.


>Fix:

	
	Manually remove /etc/security than run mergemaster again, this time
	it create directory and correctly install files under /etc/security/

	# ls -land /etc/security
	drwxr-xr-x  2 0  0  512 Jan 21 17:02 /etc/security
	# ls -lan /etc/security
	total 32
	drwxr-xr-x   2 0  0    512 Jan 21 17:02 .
	drwxr-xr-x  21 0  0   2560 Jan 21 17:02 ..
	-r--r--r--   1 0  0    689 Jan 21 17:02 audit_class
	-rw-------   1 0  0    229 Jan 21 17:02 audit_control
	-r--r--r--   1 0  0  16831 Jan 21 17:02 audit_event
	-rw-------   1 0  0    168 Jan 21 17:02 audit_user
	-r-x------   1 0  0    214 Jan 21 17:02 audit_warn
