## Issue Description

iSCSI based boot content projection which is also known as "Scalable Boot Content Projection" (SBPS) for `rootfs` and `PE` images
is supported in version CSM 1.6.0 and above. On a customer system, using `CSM-1.6.0` with `USS-1.1.x` on compute nodes/ UANs in order to support AARCH64 images,
`iscsid` and `multipathd` services are not enabled by default. SBPS will not be resilient across worker node reboots if these services are not enabled by default on compute/ UANs.

## Issue Identification

This issue can be identified by the following symptoms:

On a compute/UAN node (iSCSI Initiator) we can observe the following SQUASHFS error messages in the console log:
