Also when displaying constraints for a specified nodes the output contains rule constraints. Those should not be displayed at all as they do not match the filter.

After evaluating this issue, there are no plans to address it further or fix it in an upcoming release.  Therefore, it is being closed.  If plans change such that this issue will be fixed in an upcoming release, then the bug can be reopened.

## AFTER

[root@virt-525 ~]# rpm -q pcs
pcs-0.11.5-2.el9.x86_64

[root@virt-525 ~]# pcs resource create dummy ocf:heartbeat:Dummy

[root@virt-525 ~]# echo $?

A.) Create a location constraint with a rule on the dummy resource (only date-spec is specified).

[root@virt-525 ~]# pcs constraint location dummy rule date-spec years=2023

[root@virt-525 ~]# echo $?
0

[root@virt-525 ~]# pcs constraint location config nodes
Warning: Constraints with rules are not displayed.
Location Constraints:
  Node: virt-535
    Preferred by:
      resource 'dummy' with score INFINITY

> OK. The output of 'pcs constraint location config nodes' is slightly different than output of same command for el8. Output of this command does not contain the 'Node' section and also constraints with rules are not displayed.

B.) Create a location constraint with a rule on resource (+score property, + #uname node attribute in expression)

[root@virt-525 ~]# pcs resource create dummy2 ocf:heartbeat:Dummy

[root@virt-525 ~]# echo $?
0

[root@virt-525 ~]# pcs constraint location dummy2 prefers virt-525

[root@virt-525 ~]# echo $?
0

[root@virt-525 ~]# pcs constraint location dummy2 rule score=INFINITY "#uname" eq virt-525

[root@virt-525 ~]# echo $?
0

[root@virt-525 ~]# pcs constraint location config nodes
Warning: Constraints with rules are not displayed.
Location Constraints:
  Node: virt-525
    Preferred by:
      resource 'dummy2' with score INFINITY

> OK. Also in this case the output of 'pcs constraint location config nodes' is slightly different than output of the same command for el8. Output of this command does not contain the 'Node' section.

[root@virt-525 ~]# pcs constraint location config
Location Constraints:
  resource 'dummy2' prefers node 'virt-525' with score INFINITY
  resource 'dummy2'
    Rules:
      Rule: score=INFINITY
        Expression: #uname eq virt-525

> OK. The ability to view configured location rules still exists.

> Marking as VERIFIED for pcs-0.11.5-2.el9.x86_64
