Doc Type: Deprecated Functionality
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 via the network. While convenient, diskless boot is prone to introducing network latency in realtime workloads. With a future minor update of RHEL for Real Time 8, the diskless booting feature will no longer be supported.

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