Hello all,
I'm not sure if this is the right place to ask about this, so if I
am in error, please let me know.
Anyway, I am trying to replace the kernel that boots the RedHat
installer off of the CD. I have a known working kernel, and I replaced
the vmlinuz on the boot288.img with that kernel. I also modified the
initial ramdisk to have the modules I need. When I boot the CD, it
brings up the kernel fine, starts install (and then /sbin/loader), and
then fails with the following error (from virtual terminal 3):
kickstarting through device hdc
trying to mount device hdc
mntloop loop0 on /mnt/runtime as /mnt/source/RedHat/base/stage2.img fd is -1
LOOP_SET_FD failed: Bad file number
The kernel sees the CD-ROM drive as hdc (and it obviously boots from
it), so the device is there. In addition, the kernel certainly has loop
support. Finally, to test the integrity of the CD, I put it in another
box, and mounted the stage2.img without any problems. I am really at a
loss here.
I guess my question is twofold about this:
1. I am not exactly sure how the whole boot process (off of CD or
floppy works). I know that in syslinux.cfg, there is "append ks ...",
which I assume tells the kernel (somehow) that it should read the
kickstart file. After the kernel does it's thing and boots, I don't
really know how it passes off control to install and /sbin/loader, and
then how that passes off to anaconda. If someone could explain this
process to me, that would be a start.
2. If anyone has any ideas about why it can't mount stage2.img, that
would be extremely helpful.
(Sorry for the long e-mail).
Thank you,
Chris Lalancette
