modifying initrd.img to run custom application
Im n/w booting machine with kernel - vmlinuz and
initrd initrd.img.
I copied vmlinuz & initrd.img from RHEL4 iso.
I want to modify initrd.img so that when 2nd stage
boot loader loads initrd, my custom application gets
executed.
linuxrc in initrd.img is sym-link to /sbin/init.
My steps:
1. Renamed linuxrc to linuxrc1
2. created new linuxrc script & invoked "/linuxrc1"

Problem with PXEBOOT of diskless client -- fails to mount RAMDISK
I am having a problem with setting up diskless clients under CentOS 5.2.
I have everything working under CentOS 4.7. This is an adaptation of
the (somewhat old) Diskless Linux with PXE HOWTO by Gerd v. Egidy,
originally at the URL
http://www.intra2net.com/opensource/diskless-howto/, which is now defunt
(there is a mirror of it at

Problems reading a backup data DVD
I wrote a bunch of files to a backup DVD about two months ago and now
neither of my drives will read it. I get mount errors from "not a
directory" to something like "unrecognized file system type" and so on,
usually after a really long wait and a notice about how the drive is
write-protected (duh).
Here's what happened most recently:
# mount /dev/hdc /mnt

lvm initrd -> initramfs
I converted my lvm root initrd to an initramfs by putting glibc, lvm,
pivot_root, my linuxrc, etc. in my initramfs source file. I use ash
compiled against klibc to run my linuxrc
Unfortunately -
pivot_root . initrd
- complains -
pivot_root: Invalid argument
I suspect this may be because you can't pivot_root using a cpio
initramfs root?
If so, what should I do instead? Should I

problem loading initrd
Hi,
I am trying to load kernel 2.6.6 on a Soekris net4521 from the network
using PXE. I built my initrd with mkinitrd. RedHat nash (while running
linuxrc) hangs after mounting /proc and says "Creating block devices". I
am using the pxelinux.0 from the syslinux-2.10 distribution and the kernel
and initrd were built on redhat 9.0. I built my kernel with BLK_DEV_RAM,

It starts executing linuxrc, but gives the following errors and panics:

INITRD > MEMSIZE / 2
I?ve got a 512M machine and a 330M ( uncompressed ) initrd image. How can I
mount the ramdisk? Normal booting seems to want to copy the entire initrd
image into a Ramdisk, thus requiring 2X the memory. So what happens is the
kernel boots correctly and I get,
RAMDISK: ext2 filesystem found at block 0
RAMDISK: Loading 330000 blocks [ 1 disk ] into ram disk

play with initrd in early user space
Hi, All
I am currently learning on the early userspace(EUS) code. And my goal
is accessing initrd while in the EUS. For example: mount an initrd
with the EUS mount command, Fsck it, chroot to it, run linuxrc in it
and so on...
But depend on the code, One can not preserve a initrd image when
loading into EUS. So I must modify the EUS code to reach the goal. Can
you give me some advices about

Query on initrd
Hi
In linuxrc(on initrd), there is one 'mkrootdev /dev/root' for creating root
device, which it later mounts as root.
Where does it get the information regarding the real root device from?
Thanks

Adding USB support to a given initrd in syslinux
Hello,
I have a live-cd which has a syslinux on it and boots a linux
kernel.
It works ok and boots the kernel ok from a CD drive.
Now,I need to add support for this live-cd so that
it will boot from an external USB cdrom drive.
My bios **DOES** support booting from USB; but when
I try to boot it hangs in the middle while looking for
usb-storage drivers.

probs running stuff from initrd
Hello all
Now I may be way of whack here, so please forgive me.
I''m trying to merge xen with redhat''s config-netboot. The idea being a
kinda stateless domU. For those that haven''t seen you share a rootfs and
then bind mount all the individual files over then top, and the redhat
gui builds all the pxeboot config and stuff for you if you want a
diskless client. I

Upgrading PXE initrd.img with new kernel and drivers
Quite simply, HOW? :)
I have the pxeboot initrd.img from the RH 3.0 AS CD's. We need to put a new
cciss.o driver from HP into this initrd.img. Unforunately, the modules in
the pxeboot initrd.img we have are 2.4.21-4 and our new driver is compiled
for 2.4.21-15, so we have to upgrade everything.
I downloaded the kernel-BOOT-2.4.21-15 RPM and installed that, so I have all
those drivers. My

FYI: Article on R at IBM's developerWorks Server Clinic
Hi all,
I happened to be reviewing a Linux web site that I frequent
(http://www.pclinuxonline.com/index.php) and noted today an entry for an
article on R at IBM's developerWorks Server Clinic site located at
http://www-106.ibm.com/developerworks/linux/library/l-sc16.html. I
thought that I would pass this on as an FYI.
