Could you provide me please exact wording for the RHEL 7.4 Release Notes description of the USBGuard on IBM systems? (Known Issue/Technology Preview, which systems are fully/partially supported and so on). Thank you.
I believe we should declare Tech Preview for USB Guard on IBM Power systems. For system 390, we should make an explicit note that those platforms do not support a USB sub-system.
I'm going to suggest the following wording that should appear in the Technology Preview section of the RHEL 7.4 Release Notes:
USBGuard Technology Preview for IBM Power Platforms
USBGuard packages are provided as a Technology Preview for IBM Power LE and BE systems in this release. Full support is targeted for a later release of Red Hat Enterprise Linux.
NOTE : IBM s390x systems do not support a USB subsystem and as such, the USBGuard feature is not supported, nor provided, for those systems.
