[syslinux] Question on "root pivot" function

 Thank you for your reply. I'm sorry to bother with this, but what is
the "root pivot" function and
 where can I find doc's on it.

 From what I understand from your email the system would basically boot
twice. Once from a stripped
 kernel on the floppy disk to mount the CD, and then after the CD is
mounted it would reboot with the
 kernel and initial randisk found on the CD. Am I correct in this, or
have I left the trail.

 Thank you,

    You can boot the floppy, mount the CD, and use the "root pivot"
    which will get the result that you want.
