Diskless Client Has Kernel Panic

[xellos]

I created a server and diskless client following the directions at http://www.redhat.com/docs/manuals/e...-diskless.html.

The server is running FC3 and the client is running FC4. Both have busybox and busybox-anaconda installed on them.

The diskless client successfully acquires a DHCP IP address from the server and downloads vmlinuz and initrd. It starts executing (initrd?) and experiences the following error:

RAMDISK: Compressed image found at block 0

VFS: Mounted root (ext2 filesystem) readonly.

Freeing unused kernel memory: 144k freed

Kernel panic - not syncing: No init found. Try passing init= option to the kernel

My /tftpboot/linux-install/pxelinux.cfg/<IPaddressofclientinhex> looks like:

default fc3

label fc3
kernel fc3/vmlinuz
append initrd=fc3/initrd.img root=/dev/ram0 init=disklessrc NFSROOT=160.207.161.54:/tftpboot/diskless/fc3 ramdisk_size=10000 ETHERNET=eth0 SNAPSHOT=160.207.161.58

As you can see, I am passing the init= to the kernel, but it doesn't seem to be able to find the diskless rc script. Any ideas on where to go from here?

Just a quick note to anyone who has this problem in the future - the version of the
system-config-netboot released in the official distribution was buggy and created bad initrd files which caused the system to bomb out and die when it tried to run it.

To fix this problem, upgrade the version of system-config-netboot. This problem is well documented in Bugzilla, but unfortunately the bug reports do NOT show up when you Google. See bugzilla bug reports 16194 (rhel 4), 135411 (rhel 3), 144240 (fc3) and many duplicates.
