you can build one iso like:

make isoimage FDARGS="ignore_loglevel debug initcall_debug
acpi.debug_layer=0xffff0000 pci=routeirq apic=debug
ramdisk_size=262144 root=/dev/ram0 rw ip=dhcp
console=uart8250,io,0x3f8,115200"
FDINITRD=/home/yhlu/xx/xx/rootfs/mydisk14_x86_64_xz.xz

then use kvm to load that iso

/usr/local/kvm/bin/qemu-system-x86_64 -L /usr/local/kvm/share/qemu -m
6144 -net nic,model=e1000,macaddr=00:1c:25:1c:13:e9 -net user -smp 2
-cdrom /home/yhlu/xx/xx/kernel/tip/linux-2.6/arch/x86/boot/image.iso
-boot d -serial telnet:127.0.0.1:4444,server -monitor stdio

later could use
  telnet 127.0.0.1 4444
in another terminal to get serial console.

and initrd is converted from opensuse rescue initrd.

hope we can have scripts to create standalone initrd with updated user
program etc.

Thanks

Yinghai
