There is no problem here.
"genimage" will update the statelite/stateless initrds under
"/install/netboot..." directory,
"nodeset" will copy the relevant initrd from "/install/netboot.." into
"/tftpboot/xcat/osimage..." with the name unmodified,that is, copy
"statelite-initrd.gz" if "osimage.rootfstype=nfs", copy
"stateless-initrd.gz" if "osimage.rootfstype=ramdisk", finally update the
boot files under "/tftpboot/xcat/xnba/nodes/...".
so if you changed the statelite osimage definition, you should always run
"nodeset" to update the relevant things.

this line shows that
"/tftpboot/xcat/osimage/rhel64nophi/initrd-stateless.gz" will be used as
the ramdisk based statelite initrd.

when you use "nodeset ... statelite", it will use a default osimage "
rhels6-x86_64-statelite-compute". what i can get from this process is that
there is no problem in the statelite-initrd.gz generated by "genimage".
So my advice is that you shold make sure that the statelite-initrd.gz
after "nodeset" under "/tftpboot/osimage..." is the same as the one under
"/install/netboot..." generated by "genimage".
good luck
