With the xcat install what ends up in the /etc/modules.conf? This
will specify any special order and is used by mkinitrd.
THe LCFG install calls mkinitrd after creating this file so it
should hopefully be possible to emulate what xcat is doing.
All this is in the redhat-73-cfg.h
Eg adding this to a nodes profile will define the modules.conf exactly.
hardware.modlist line1 line2 line3
hardware.mod_line1 alias eth0 eepro100
hardware.mod_line2 alias scsi modfishy
Later on in the install the following is called.
chroot /root mkinitrd PRELOAD_MODULES -f /boot/initrd-KERNEL_VERSION.img KERNEL_VERSION
The PRELOAD_MODULES could be set in the site-cfg.h and has a format like
--preload modb
