cant find filesystem /dev/root

[Lane Brooks]

I am using the latest image-creator tool from the git repo to create an
custom fedora image based on fedora 8.

When I try to boot either from the physical image or in qemu, I get the
following error:

mount: could not find filesystem '/dev/root'

and then eventually switchroot fails and the system hangs.  I have tried
the original kernel and the latest released kernel.  I have rebuilt
initrd based on hda1, sda1, etc. in the /etc/fstab file and get the same
problem.  I have tried grub, extlinux, and even booting directly in
qemu.  No matter what I get this error.

The only thing I have gotten to work is to download a vanilla kernel and
build and install it manually.  It seems as though the fedora kernel
does not find the ide drives, although I cannot verify this because the
text scrolls too quickly for me to see.

Anyone know what the problem is?  I am not sure if this is the best list
to ask this question, so perhaps even suggesting a more appropriate list
would be helpful too.

Thanks,
Lane Brooks

I finally found a way around that I am posting to the list in case it 
helps someone else.  Things started working when I started building 
initrd using the --with ata_generic --with libata options.

Can you specify these options in the kickstart file while using
revisor? How is the syntax?

Thanks!

Not that I am aware of.  The way I do it is to mount the image after it 
is done, use

mount --bind /sys <path_to_image_mount>/sys

to mount sys, update the fstab to point to my label:
LABEL=mylabel /   ext3  defaults 0 0

then run chroot into the mounted image

chroot <path_to_image_mount>

and then run mkinitrd

/sbin/mkinitrd --with libata --with ata_generic 
/boot/initrd-<kernel_ver>.img <kernel_ver>

I am not sure if there is a better way.
