Description of problem: When remediating any of the Restrict Partition Mount Options the remediation fails in offline mode i.e. xccdf_org.ssgproject.content_rule_mount_option_dev_shm_noexec. The remediation script checks the /proc/mounts which is unavailable even if the fstab file has been created. Version-Release number of selected component (if applicable): 0.1.63 How reproducible: Steps to Reproduce: 1. Configure a blueprint with moutnpoint options and oscap configuration 2. Build image with osbuild-composer Actual results: Remediation does not run at all for this since the evaluation result is unknown. Expected results: Offline remediation of the /etc/fstab file Additional info: I: oscap: Evaluating definition 'oval:ssg-mount_option_home_nodev:def:1': Add nodev Option to /home. I: oscap: Evaluating partition test 'oval:ssg-test_home_partition_nodev_optional_yes:tst:1': nodev on /home optional yes. I: oscap: Querying partition object 'oval:ssg-object_home_partition_nodev_optional_yes:obj:1', flags: 0. I: oscap: Creating new syschar for partition_object 'oval:ssg-object_home_partition_nodev_optional_yes:obj:1'. I: oscap: I will run partition_probe_main: E: oscap: Can't open /proc/mounts: errno=2, No such file or directory. W: oscap: Can't receive message: 125, Operation canceled.

The way we evaluate and remediate mount point options in CaC content has been changed to accommodate 'offline' systems. The content would now properly detect mount point configuration and change it accordingly in the IB pipeline environment. https://github.com/ComplianceAsCode/content/pull/10200
One of our customers is experiencing the issue while applying CIS Level 1 Server while using osbuild-composer for RHEL 8.8 as well as RHEL 9.2. It also has to be fixed for RHEL 9. Setting the severity as High as we have no workaround to suggest.
