Hi!

Looks fine! Could you post the working script to the list? Maybe it's
worth at least to mention it in the FAQ. Maybe it's even a good way to
to include this way as default boot behaviour for initrd kernels.

I'm sorry but I think I don't understand you. You say it only works for
scsi (or ide-scsi) devices?

Hm, good question. My understanding of pivot_root is that it tells the
kernel to use another mounted filesystem as new rootfs when the script
exits. This is a great advantage over the old real_root_dev approach in
earlier kernels because you had to echo the device minor and major
numbers(!) into a file called real_root_dev in the procfs of the initrd.

So my understanding of this is that you don't need to have the
directories in the root dir of the bootcd since the script runs in the
initrd and this fs end up in /initrd of the cdrom. But maybe I'm
completely wrong. Could you give it a try?

So long
Thomas
