Syslinux - Apr 2005 - pxeboot to runlevel 4

folks,


Im trying to boot to runlevel 4 explicitly, using this stanza: ie with a 
single 4 at end of APPEND line.

LABEL   2.6.11-r10c2-soekris-v1
  MENU LABEL    ^j.  runlevel 4  2.6.11-r10c2-soekris-v1
  # 4 MENU DEFAULT
  KERNEL        vmlinuz-2.6.11-r10c2-soekris-v1
  APPEND        console=ttyS0,19200n81 root=/dev/nfs 
nfsroot=192.168.42.1:/nfshost/foo 
nfsaddrs=192.168.42.100:192.168.42.1:192.168.42.1:255.255.255.0:soekris:eth0 
panic=5 initrd=initrd-2.6.11-r10c2-soekris-v1.img 4


This usually works for grub on my laptop, but doesnt in pxelinux 308-pre7.
I havent gone back to earlier versions, I wanted to check my 
understanding 1st.

Is a single number on APPEND line a universal way (grub, lilo, pxelinux) 
to specify a runlevel ?
I saw no mention of it in linux-*/Documentation/kernel-parameters.txt,
and it seems like an omission if it is actually true.

theres also no mention in man inittab whether 'initdefault' can be 
overridden
by kernel-command line, though I know Ive done it.

the command-line received by the kerenel is (for another similar stanza)

Kernel command line: console=ttyS0,19200n81 root=/dev/nfs 
nfsroot=192.168.42.1:/nfshost/foo 
nfsaddrs=192.168.42.100:192.168.42.1:192.168.42.1:255.255.255.0:soekris:eth0 
panic=5 initrd=initrd-2.6.10-r10c2-soekris-int-v1.img 
BOOT_IMAGE=vmlinuz-2.6.10-r10c2-soekris-int-v1

The '4' appears to be getting trashed by the BOOT_IMAGE info appended 
automatically.
I have no IPAPPEND statement in the pxe boot config

Yes.
But neither the boot loader nor the kernel are involved by this. This paramter 
is checked by the init process (pid 1, usually /sbin/init).

Check ?cat /proc/cmdline?.
Maybe your append line is shorten.
Try to set the "4" earlier in the append line.
