Additional related issue: On my previous dhcpd setup I'd setup a new 
system to boot and install from the network with the pxeboot command and 
it would create the pxelinux.cfg/<host identifier> file with the kernel 
that's available from tftp and an append line.  I can't find the pxeboot 
command anywhere in Rocky Linux 8.x.  I can hand jam those files if 
needed but was curious if the utility is available somewhere. There's a 
pxeos.xml file in that setup and it's also seemingly not available in 
RL8 or kea.
