similar to: [WIP] rebuild initramfs when content changes

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

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.

(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

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).

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

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

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

Last patch for now. This gets gen_init_cpio into a state where it can pick up a "kinit" binary from usr and stuff it into the cpio archive as /sbin/init. This is obviously a crock, but it suffices for testing until something sane is done about integrating klibc into the kernel tree. The patch also adds a bit of instrumentation to initramfs.c, to try to help flush out bug 740.

Following patch improves integration with kbuild. With a future kernel (2.6.14-rc) it now has working support for 'make clean'. Included is an example of how to compile an early userspace program. I selected gzip as the most simple one for this - and left out all the links to different names (gunzip etc.) Before proceeding with this I need some inputs on what functionality is required by

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? Initramfs is a ramfs into which

Factor out all kernel specific path's (those containing usr/) into two variables: KLIBSRC + KLIBINC. Set the variables in a kernel spcific Kbuild file.

Hi friends, Again i don't know how to pass multiple arguments from php file to r scripts. Please have a look at this link ; it gives a very simple explanation of passing variables from a PHP page to r scipts.Because i have done the same thing.

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 don't know if other systems are concerned as well but it's at least a problem for Cygwin that the uid of the privileged user is fixed to the constant 0 in the OpenSSH sources. A month ago I ported Paul Vixie's cron to Cygwin and he's using at least a define for that: #define ROOT_UID 0 which simplified the porting vastly. May I propose to change the usage of uid 0 in

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

Hi, I 'am trying to launch linux kernel 2.6.7 with initramfs.
