Yes, this sounds like the correct explanation! Our RHEL5.6 PXE/TFTP/NFS server is certainly configured for NFSv3. I haven't explored the NFSv4 approach though. How can we tweak the CentOS6 Kickstart installation to explicitly request an NFSv3 service in the PXE config file: kernel CentOS-6-i386/vmlinuz append load_ramdisk=1 initrd=CentOS-6-i386/initrd.img network ks=nfs:130.226.86.4:/u/rpm/kickstart/ks-centos-6-clean-i386.cfg To rephrase my question: Where do we find documentation for the vmlinuz append flags shown above, in particular documentation of the ks=... flags? Hopefully there'll be some way to force an NFSv3 mount in stead of the default NFSv4? Or perhaps we need to use http: and stop using nfs: with CentOS6? Thanks, Ole
