similar to: [PATCH 2.5.69 3/3] Bandaids for gen_init_cpio and initramfs

I've been having an exchange of e-mails with Bryan O'Sullivan regarding this problem. I thought it time to bring it to the list. I've run into a problem where my initramfs archives get this during bootup: checking if image is initramfs...it isn't (ungzip failed); looks like an initrd The same .cpio archive works if I don't gzip it. I stuck a bunch of debug statements into

I've googled to try and find discussion of this topic but didn't see any results particularly interesting... Is there any particular reason the kernel has gen_init_cpio instead of just using cpio itself? I'm working on some changes that would involve just cpio-ing the entire usr/root subtree as the initramfs image (instead of gen_init_cpio having to know ahead of time what files to

(Apologies to klibc@zytor.com for the re-send) This patch makes gen_init_cpio generate the initramfs_data.cpio from a file which contains a list of entries: file, dir, nod. I swapped the order of filename/location for the file arguments so that it would be more uniform with the dir and nod tyes. [thayne@torch linux-2.6.8]$ usr/gen_init_cpio --help ERROR: unable to open '--help': No such

This fix has been implemented in preparation for the upcoming klibc merge in -mm. But as it fixes a real (but rare I hope) bug in vanilla kernel it will be added to my pending 2.6.17 kbuild queue. I've done quite some changes to the gen_initramfs script and being shell programming newbie review by more experienced shell hackers would be appreciated. I did a git mv

hpa notified me in private mail that we have an issue that when building initramfs - if the content changes (say kinit) then the initramfs will not be rebuild. The solution I have come up with is to let make check all the files included in the initramfs and rebuild it if any files are newer than the initramfs and also rebuild if arguments changes (root_uid). In same process the usr/Kbuild file

Generate dependencies almost like done by fixdep in the kernel. This teaches make to rebuild cpio image when content has changed. Also restructured usr/Kbuild a little so we better utilise parallel makes (dash, gzip, utils and kinit are now build in parallel).

This patch removes support for use of NFS as a root filesystem from the kernel. It also updates the documentation to reflect this. b/Documentation/nfsroot.txt | 97 +++--- b/arch/arm/def-configs/a5k | 1 b/arch/arm/def-configs/adi_evb | 1 b/arch/arm/def-configs/adsbitsy | 1 b/arch/arm/def-configs/anakin | 1

Harcoding default content of initramfs in the gen_initramfs_list.sh script seems ackward.

Hi Bryan and other klibc people. I have taken a stamp on the Makefiles for klibc, this is what I came up with. 1) No longer recompile on every invocation 2) Correct checking on dependencies 3) Simpler makefile syntax (almost all over the place) I compile-time tested it only. Two open issues: a) Do we realy use .a files for initramfs. I renemed that to the executable. b) I renamed

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 are klibc and initramfs?

I'm curious, and perhaps a bit naive about this stuff. I'd like to know the reason for having a klibc-$HASH.so version which the shared apps are linked against. It makes it less simple to build a static initramfs file list to use. Currently, one has to read the libc.so.hash file to build the filename, something that can't be done in a file list passed to gen_init_cpio unless it's

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.

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 is the upcoming merge of klibc and I missed a good

To make it more obvious where the files are supposed to end up move files so they reflect the directory structure in the kernel: mkdir scripts mv kernel/Kbuild.* scripts/ mkdir usr mv kernel/Kbuild usr rmdir kernel Furthermore: - updated cp-to-kernel to refelct new directory layout - teach cp-to-kernel to place gzip right under usr/ - Add '#' in front of comment in usr/Kbuild --- I

I saw a few people mentioning they were running or trying to run asterisk on Xen. Last night I checked out v1-0, compiled, ran "make install; make samples", then started asterisk with "asterisk -vvvvc". Several modules refused to load giving this error: [chan_sip.so]May 22 13:48:41 WARNING[4308]: loader.c:258 ast_load_resource: /usr/lib/asterisk/modules/chan_sip.so:

gen_initramfs_list.sh failed to generate a dependency list when it was supplied the -d option. Restructured gen_initramfs_list.sh to support dependency info with -d. This also fixes a bug where we did not properly process when more than one dir was specified. Finally update dependency info for the -d case (list_default_initramfs) In usr/Kbuild remove "" around CONFIG_RAMFS_SOURCE so the
