RHEL4U6 - system-config-cluster looks for /usr/sbin/cman_tool instead of /sbin/cman_tool

Description of problem:
system-config-cluster-1.0.51-2.0.el4_6.1 looks for /usr/sbin/cman_tool which doesn't exist with cman-1.0.17-0.el4_6.3.
I have tested the latest builds from brewroot and get the same result:
Appears that cman package does not create the required symlink that is needed to be compatible with system-config-cluster(RHEL5 does not require symlink since default location is in /usr/sbin/cman_tool)
Here is a related BZ on RHEL5 issue:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Steps to reproduce:
1. Configure cluster.conf
2. Start cluster services (ccsd, cman)
3. Open system-config-cluster and click on Management tab
Error message stating "Node information is temporarily unavailable. Here is the error message: A problem was encountered when attempting to get information about the nodes in the cluster: /bin/bash: /usr/sbin/cman_tool: No such file or directory"
Management interface available since cluster is started and member is joined
# ln -s /sbin/cman_tool /usr/sbin/cman_tool
Additional info: In /usr/share/cluster/CommandHandler.py, /usr/sbin/cman_tool appears on the following lines: 78, 82, 216, 220, 239, 243, 284, 288, 313, 317, 479, 485
The issue appears to be related to the change in RHEL5.
I believe the system-config-cluster package was based on the RHEL5
system-config-cluster which uses the path /usr/sbin/cman_tool instead of RHEL4
location of /sbin/cman_tool.
The package system-config-cluster-1.0.45 uses the correct RHEL4 path
I believe a symlink is needed on package install.
$ ln -s /sbin/cman_tool /usr/sbin/cman_tool
This system-config-cluster version seems not compatible with RHEL4, the "Cluster
Managemnt" tab doesn't work as expected: Name and Status columns on the Members
section show incorrect values.
From /usr/share/system-config-cluster/CommandHandler.py it seems that NodeData
instances aren't initialized in the right way (at least for DLM clusters).
system-config-cluster-1.0.51-2.0 + bz398291 fix works fine for us.
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux maintenance release. Product Management has requested
further review of this request by Red Hat Engineering, for potential
inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update
I can confirm that this bug exists. The severity should be increased, because it
makes system-config-cluster unusable (without the symlink workaround).
So much for release QA, hey folks!
