...chroot is implemented via LD_PRELOAD, it ends up running the native dynamic loader, and of course the appliance doesn't have an ld.so.cache early in building. The effect of this is that, while building the appliance, you are suddenly hit with an error like this: ,---- | Complete! | ++ basename initramfs/lib/modules/2.6.33.3-85.fc13.x86_64 | + kversion=2.6.33.3-85.fc13.x86_64 | + febootstrap-run initramfs -- /sbin/depmod -a 2.6.33.3-85.fc13.x86_64 | + febootstrap-run initramfs -- mkdir -p --mode=0777 /sysroot | mkdir: error while loading shared libraries: libselinux.so.1: wrong ELF class: ELFCLASS...

Hi, Here's a try at writing an initramfs HOWTO. This is basically a write-up of a number of interesting emails I collected over time. It could probably use an editor, more fact-checking and a bunch of other good things, but it should be better than nothing ;-) Daniel -------------- next part -------------- INITRAMFS HOWTO 0) What a...

--32u276st3Jlj2kUU Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi all (two) klibc hackers! 8) Here's the stuff I've been using to build an initramfs image and run it on one of my machines. Unfortunately, the "init" script contains hard coded information about where to find the root, etc, but it should give people a working base to start from. It requires at least klibc 0.51, and is loosely based on what the kernel does today, minus...

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? T...

Hi, The attached patch is an update to the latest klibc (I just checked a few bits into CVS) which adds support for initramfs. Since it contains bits that aren't available yet on the main site, I've also put a tarball up which contains only what's in the latest CVS. The initramfs stuff is what I use here to boot one of my machines; it works for me, but probably won't work without modification for you....

Hello what is the difference between busybox and klibc? Say, I want to use an initramfs in order to mount root over nfs, I can choose to use klibc with ipconfig and nfsmount? But I can also choose to use busybox with ifconfig and mount. So what's the difference, and why and in which case one is preferable to the other? If it's a FAQ, I'm sorry, just give me the link Th...

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.

Harcoding default content of initramfs in the gen_initramfs_list.sh script seems ackward. Move it to a file named: usr/initramfs.default This also fixes a small bug when no arguments was passed to CONFIG_INITRAMFS_SOURCE (-d was passed twice to the script) Idea and bug report from: "H. Peter Anvin" <hpa@zytor.com> Si...

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/

initramfs-tools git repo: git clone git://git.debian.org/kernel/initramfs-tools.git initramfs-tools is an hookable initramfs generator. It can boot on NFS, LVM2, md, LUKS, dmraid, oldstyle devices, .. The generated initramfs is generic, but can explicitly be tuned for small. It is actively deployed in Debi...

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...

At present the configuration items for initramfs is located in: Device drivers | Block Drivers | xxx This is maybe not the most natural place to have it. So with the following patch it is moved below "General setup", and relevant config items are collected in a file with a new home in usr/. The original reason why I looked into this...

Commit?73fb321a5d56b ("lua: make initramfs structures full userdata objects with methods") broke my boot script, requiring a workaround along the lines of the patch below: Is this an intentional user-visible change?

systemd supports switching back to the initramfs during shutdown in order to make it easier to clean up the root file system. This is desirable in order to allow us to remove keys from RAM before rebooting, making it harder to obtain confidential information by rebooting into an environment that scrapes RAM contents. --- debian/changelog...

Hi all I'm trying to boot with initramfs I build my own root fs, and the kernel build links it, I have double checked this when the kernel boots unpack_to_rootfs() returns no error, so it continues and .... when It tries to mount the rootfs it tries to mount from an IDE device (where the kernel was built from), and not from the init...

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) ?

....02 BIOS" I am booting in legacy (bios) mode on a gpt partition on my laptop. It's a HP ENVY dv7. CPU: Intel i7, BIOS: InsydeH2O version: F. 12 With syslinux 4.06, it boots flawlessly. With syslinux 6.01 and 6.02, the welcoming message flashes up, then the automatic booting of the first initramfs. It's a rather large initramfs. Straight away the booting process looks different than with 4.06. The periods that were showing progress in loading the initramfs now does not increase as the initramfs is loaded. So, only three periods after each initramfs. Once the last initramfs is loaded,...
