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

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 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.

Hi I had some doubts regarding what all the init application should do: >> so, that should that application do? >> - mount /dev/hda1 /new-root >> - cd /new-root >> - run-init 1. Of what I understand, before exitting, init should mount the realroot and execute the init process. Is realroot the '/' or the empty directory created (in the cpio archive) ?

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 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, RAMFS, TMPFS,

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

Hi, I want to customize initrd so that I can run my application once vmlinuz loads initrd. (similar to dos booting - dos runs autoexec.bat) I copied vmlinuz & initrd from RHEL4 ISO. Mounted initrd renamed 'linuxrc' exe to linuxrc1 created new script linuxrc called linuxrc1 from linuxrc script called my application from linuxrc script. But I receive "kernel panic" error:

The attached patch breaks out the /dev/root device node creation from do_mounts, placing it in it's own utility (called mkrootdev). This is worthwhile, as certain setups will need the device node there to run fstype and load a proper module (or other things). No, it does not currently configure raid devices.... I didn't know if that made sense in there or not.... Let me know what you

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" from

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

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, 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 *

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

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

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 .
