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

Hi I am trying to have a built in initramfs along with the traditional initrd. So I mount the initrd from the initramfs, but am facing problems in trying to run the 'linuxrc'. Following are the issues: 1. I mount the initrd from the initramfs and exceve 'linuxrc'. It starts executing linuxrc, but gives the following errors and panics: Red hat nash version 3.4.42 starting

Hello, I would like to know if initrd is here to stay, now that klibc and initramfs are ready. As the multipath-tools maintainer, I'm facing the choice to 1) put the multipath configuration tool in the initrd * dynamic binary is possible * storage hba drivers as modules loaded * no klibc limitations (no mntent for libsysfs ...) 2) put the multipath configuration tool in the initramfs *

Hi I am an engineer who is making communication systems. I have a board(made by Kontron ltd, Intel CPU, currently with diskless ) that is used in compactPCI. I boot that board with network PXELINUX method and currently using NFS. But I don't want to use NFS and I want to make and use ram disk image. That means I want to use a ram disk as /. Currently I made a initrd by ltsp_initrd_kit. What

hi ya syslinuxerz - i've been slowly working on a making a custom bootable standalone usb-stick with X11 and kde - it's basically builds itself off of a slackware-10.1 server - create a custom initrd.gz ( /dev/ram0 ) http://linux-boot.net/Bootable/InitRD/ - create a custom rootfs.gz ( /dev/loop0 ) http://linux-boot.net/Bootable/RootFS/ - create X11 and kde loopfiles

Dear All, I have a following query: - My initrd image is created using ext2 filesystem. - The filesystem type of / is specified as ext3 in /etc/fstab file. - I dont mount the real root during execution of linuxrc because I referred some documents saying that if you dont mount real root from linuxrc the kernel will mount it after linuxrc is finished. - The system boots up successfully, mount

This is most exceedingly weird boot/shutdown sequence that I used once, and can't find a way to adapt to initramfs. Since you guys are trying to adapt all mechanisms that use initrd to using initramfs, this should interest you. initrd has (all binaries static): /bin: init halt mount poweroff pivot_root reboot sh umount /etc: fstab haltrc /dev: null zero tty tty0 tty1 console->tty0 hda1

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

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 And then I never see the light of day after

I'm not sure when exactly this started, but currently when I specify a ramfs image via the initrd line in grub, kinit picks it up as an initrd and tries (and fails) to unpack it and run linuxrc from it. I'm assuming this is not the intended behavior. Can anyone point me into the proper direction for unpacking an initramfs image ontop of the in-kernel image? Currently, I am using kernel

Hi 1. Is it possible to load an initrd from initramfs ? How would you do this if the initramfs is being loaded dynamically in the kernel (ie having the initramfs as initrd ) Because in this case, you will say root = /dev/initrd and specify 'initrd' as your 'initramfs source file' How will you specify the second initrd source? Thanks Rachita.

Hi, I 'am trying to launch linux kernel 2.6.7 with initramfs. My pxelinux.cfg/default file looks as follows: default a1 prompt 1 timeout 600 label a1 kernel vmlinuz-2.6.7-1 append initrd=initramfs_data.cpio.gz root=/dev/ram0 init=/linuxrc Kernel image vmlinuz-2.6.7-1 and initramfs_data.cpio.gz was loaded succesfully by pxelinux. Kernel says: checking if image is initramfs... it is but

Im pxebooting target machine with vmlinuz & initrd. Once vmlinuz loads initrd, Im calling "/bin/sh" from linuxrc script so that I get command prompt. But my machine is not connected to network. # ping 192.168.25.2 connect: network is unreachable #ifconfig -a can not open /proc/net/dev : No such file or directory my /proc is empty. Please advice how to customize initrd image to

I have finally gotten one version of windows 2003 r2 x64 installed as a guest. The bad news is no network. The network tab says it''s a realtek 8139 when I know it is a intel. I tried downloading the intel drivers and they wont install says it''s the wrong hard ware. Is this common that it uses a 8139 as a generic network card? Also the network card shows The

Hi, I hope this is the right list for initramfs questions. First I noticed: with initrd I can use real-root-device and pivot_root mechanisms. with initramfs only pivot_root works. My init (or linuxrc) scripts end like this: mount -t xfs -n -o ro /dev/mapper/root /new-root umount -n /sys || true umount -n /dev || true umount -n /proc || true cd /new-root pivot_root . initrd exec chroot .

Hello, I'm trying to fix netbooting and I got quit far. Before this, it reported that it had no root disk, I fixed this by specifying my initrd. Nou it crys's: Kernel panic: I have no root and I want to scream I think I made the mistake whit the creation of the initrd file. What should I put in it except the /linuxrc. I put a echo "TEST" in de /linuxrc to see if it runs, in

Hello Is there a skeleton for an initramfs, like mkinitrd do for an initrd? An archive where all I could need for my initramfs could be present, with a shell script ready to fill in with my work to be done. Thanks Eurolines : Voyagez au meilleur prix : http://www.alinto.com/pub/

Hi I am looking at inserting functions in the early user space and want to use initramfs for this. I understand this can be achieved using 'initrd' or by making changes in the 'usr/gen_init_cpio.c' file. Can someone kindly give me pointers as to how to go about this. I am looking at the 2.6.x kernel. Thanks Rachita.
