Dear all

I am a new in kernel development and using Fedora 9. Sometimes a make certain changes in kernel, compile it and boot using qemu.

qemu -kernel vmlinuz-2.6.*.* -initrd initrd-2.6.*.*.img -hda /bin/true

It boot the kernel and leave me with message root can't be mounted.

I want to make modification in initrd so that, after loading kernel it drop me at shell like enviroment in qemu.( similar to what we get in 'linux rescue') . If i got any temporary shell enviroment i can test my newly modified kernel without restarting system.

Thanks

Although the "initial ramdisk" environment does exist to handle "that very strange state when a kernel has not quite yet booted," I am not personally aware that it offers any sort of a shell.

Nor that it necessarily ever could.

(He said, waving his hands furiously...)

Busybox will be handy for you to create a Ramdisk image with shell and other basic commands. Look out for the procedure on internet for creating ramdisk images with busybox.
