[syslinux] My kernel panics when I add the kickstart line with append - could I get some advice?

[Jeff Silverman]

I am trying to add a kickstart file to my automatic installation and 
make it more automatic.  However, when I comment out the append ks=... 
line in the example below, the computer boots properly.  If I uncomment 
that line, then I get a kernel panic:

VFS: Cannot open root device "" or 09:02
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 09:02


I don't understand the problem.  I thought that the root file system was 
attached with the append initrd=initrd.img directive.  It works if I 
comment out the ks line.


## Perform a local boot by default
#default local
 
# Perform a network boot by default
default network
 
# Always prompt
prompt 1
 
# Display the bootup message
display pxeboot.msg
 
# Boot automatically after 30 seconds in tenths of a second
timeout 300
 
label local
# On PXELINUX, specifying "LOCALBOOT 0" instead of a "KERNEL" option 
means invoking this particular label will cause a local disk boot 
instead of booting a kernel.
# The argument 0 means perform a normal boot.
        localboot 0
 
label network
        kernel vmlinuz
        append initrd=initrd.img
# The kickstart file is /home1/rhel3/test-kickstart.ks on NFS server 
192.168.1.1
        append ks=nfs:192.168.1.1:/home1/rhel3/test-kickstart.ks
#       append ksdevice=eth0
        ipappend 1




Many thanks,
