I've got the same problem... how did you solve the nfs mount problem ?? I suspect that the 'mount' binary in the initrd does not handle NFS mounting somehow.... where does 'mount' come from ? is it from busybox or from util-linux ? regards
I haven't solved it conclusively yet. I unpacked the initrd.img and replaced mount with 'busybox mount' for the first nfs mount. This works, and the system boots to a login prompt, but there were enough other errors to make me think this wasn't a good solution. I looked at the script which creates the initrd.img and it just does a copy of /bin/mount. My suspicion is that /bin/mount should be enough, but it needs something else to make the nfs mount work correctly. I plan to try again, but this time with a more or less full FC6 installation on my diskless image rather than the minimal one I had before. I've also thought of putting mount.nfs into the initrd.img and using that. Both of these will have to wait until at least the weekend though. Chris
