TALM SNO Backup Fails on Managed Cluster Running CoreOS 9.2

CoreOS 413.92.202303061740-0

Always

1. Hub Cluster running OCP 4.13, TALM 4.13
2. Managed spoke cluster installed with latest OCP 4.13 nightly build which runs CoreOS 9.2
3. Create a change to the managed cluster config in Git which causes a policy to become noncompliant.
4. Create a CGU on the hub cluster specifying the target spoke cluster and managedPolicy
5. Set backup: true in CGU
6. Enable CGU

CGU will fail with "Unrecoverable error".

The managed clusters backup pod log will show the following errors:

-----
snapshot db and kube resources are successfully saved to /var/recovery/cluster
[sender] readlink_stat("/etc/adjtime") failed: Permission denied (13)
[sender] readlink_stat("/etc/aliases") failed: Permission denied (13)
[sender] readlink_stat("/etc/chrony.keys") failed: Permission denied (13)
[sender] readlink_stat("/etc/exports") failed: Permission denied (13)
[sender] readlink_stat("/etc/gshadow") failed: Permission denied (13)
-----

This error is due to selinux configuration. Setting selinux to "permissive" on the managed cluster fixes this problem.

Backup is successful. CGU is successful.
