Doc Text:	.Installing RHEL for Real Time 8 using diskless boot is now deprecated Diskless booting allows multiple systems to share a root file system through the network. While convenient, diskless boot is prone to introducing network latency in real-time workloads. With the 8.3 minor update of RHEL for Real Time 8, the diskless booting feature is no longer supported.

Received approval from Product Management to remove references to diskless operation for the 8.2 RT release

This is section 2.2 of the installation guide:

That will probably break OpenHPC's warewulf and xcat diskless operations, unless these 2 frameworks are not relying on this deprecated feature.
