Client (SWC) Installation
The initial client installation was performed using the hard disk drive that came with SWC-001. The host was booted via PXE boot and the installation performed by the kickstart mechanism from either the new server-1 or the old serv-1.
After the kickstart installation, the system image was rsynced to server-1 to become the first diskless image (RHEL-22.214.171.124). The initial installation was for a late revision of RHEL 7.6 and has progressed via system updates to RHEL 7.9 (12/11/20).
At some point after the diskless boot was working, the hard disks were removed from the SWCs.
