The DMS service uses /usr/bin/mlnx_qos to handle QoS configuration (trust mode and PFC settings). The mlnx_qos Python script internally depends on the 'ps' command to check running processes.

The STIG-hardened RHEL images strip out procps-ng for security hardening, causing QoS configuration to fail with:
FileNotFoundError: [Errno 2] No such file or directory: 'ps'

This results in NicDevice runtime configuration failures with the error: "failed to get trust mode: failed to run get path command: exit status 1"

Add procps-ng to the nic-configuration-daemon STIG RHEL image to resolve this dependency. The Ubuntu STIG images already include procps and are not affected.

Greptile Summary

Added procps-ng package to RHEL STIG daemon image to fix QoS configuration failures. The DMS service uses /usr/bin/mlnx_qos Python script (added in commit fbfe19c) which internally depends on the ps command to check running processes. STIG-hardened RHEL images strip out procps-ng by default for security hardening, causing QoS configuration to fail with FileNotFoundError.

• Fixes runtime configuration failures for trust mode and PFC settings
• Change is minimal, targeted, and necessary for functionality
• Ubuntu STIG images unaffected (already include procps by default)
• Aligns daemon image dependencies with operational requirements

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The change is a single-line addition to install a standard system utility package (procps-ng) that provides the ps command. This is a necessary dependency for the mlnx_qos script that was recently added to handle QoS configuration. The fix is well-documented, targeted, and addresses a clear runtime failure. No code logic changes, no security concerns with adding this widely-used system monitoring package.
• No files require special attention
