Hi Peter & others. Here are three patches that does the following: #1 - Update kbuild part of klibc so make clean works Adds gzip including a sample kbuild file #2 - Factor out definition of usr/ to two variables #3 - Move kbuild files to reflect location in the kernel As requested in earlier mail I need a bit of guidiance of what you expect from the kernel integrated parts of klibc.

(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.

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.

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code. This is also available as a git tree at:

Hi , One of the things I am working on requires me to have a kernel and an initrd (as root filesystem , based on busybox) in one single image. I am trying to use initramfs for this, but there are a few things that I just can't figure out. As a test, I made a cpio archive of my own for the kernel source (plain 2.6.0-test5). Everything gets unpacked just fine during boot. Somehow I was

Please be aware that I HAVE NOT TESTED THIS PROGRAM... please try it in a "safe" environment since for all I know it could nuke your "real root" by mistake. -hpa
