[syslinux] lpxelinux.0 issues with larger initrd.img files from RHEL >= 7.5 on UCS servers?

A_ Instead of 6.03, try 6.04-pre1 (not pre2 and not pre3, but pre1). 
Please remember to change _all_ related files to the same version, not 
just lpxelinux.0.

Alternatively (and in many cases, even better) you could try current 
Debian's "Unstable" packages, which are "more up-to-date" than 
6.04-pre1.

B_ In the configuration file, instead of using:

###
LABEL mylabel
KERNEL mykernel
INITRD myinitrd
APPEND myoptions
###


try:

###
LABEL mylabel
LINUX mykernel
INITRD myinitrd
APPEND myoptions
###


and/or also try:

###
LABEL mylabel2
COM32 linux.c32
APPEND initrd=myinitrd myoptions
###

(Reminder: use linux.c32 and the lib*.c32 modules from the same version 
as lpxelinux.0 and ldlinux.c32.)

Using the LINUX directive and/or the linux.c32 module (instead of the 
KERNEL directive) _might_ help in some "(files') size too big" (or 
similar) cases.
