Bug 135445

This is part of a split up of bug #135382

Problem varies depending on version (S93, S10).  When doing a PXE-booted
installation, autoyast does not function properly if the autoyast XMl config is
not specified in the initrd.  

Using this config:

(pxelinux config:)
LABEL suse10-TEST
  MENU LABEL TEST -- (network install) Install SuSE 9.3 from SuSE 10 from
autoyast config
  KERNEL boot_images/OS/SING/suse10-install/linux
  APPEND initrd=boot_images/OS/SING/suse10-install/initrd-test
ramdisk_size=131072 server=endor info=file:/info.ilm
autoyast=http://adroit/~estair/autoyast.desktop.sda.SING hostname=


(info file-info.ilm:)
textmode=1
splash=verbose
nameserver=10.66.1.108
InstMode=nfs
Serverdir=/san/dept/sio/linux/os/suse/9.3/dist

(linuxrc.config:)
KernelPCMCIA:   1
UseUSBSCSI:     1
Product:        SUSE Linux
UpdateDir:      /linux/suse/x86_64-9.3
MemLoadImage:   204800
MemYaST:        92000
MemYaSTText:    64000
InstallDir:     /boot/inst-sys64
RescueImage:    /boot/rescue64
RootImage:      /boot/root-suse10
ModuleDisks:    0


With this setup the installations continues up until the bootloader, after
which it fails for some unspecified reason (not running y2debug=1 at that
point).  Grub IS present in the mounted image, but menu.lst is not written
correctly according to the xml.
