...it takes the same list. 1.3) Using cpio Running "find | cpio --format=newc -o | gzip > archive.cpio.gz" will create a cpio archive of that directory's contents that can be used as an initramfs. See also: Documentation/early-userspace/README 2) Contents of the initramfs When an intramfs archive is found during boot, the kernel will try to start /init. This is the only file the initramfs actually _needs_. Everything else is optional, depending on what you want the initramfs to do. Typically you would want /init to be a shellscript which mounts the root and other filesystems, loads...

I once ran into a quite similar problem, but solved it with a simple kernel that ran on every machine and some initramfs magic with a statically compiled kexec contained in intramfs that loaded the special kernel (in this case via network) and kexec'd it. This should work for your problem as well. If you already built kernels for every macine, it should be OK to modify some 20 lines of shell code for the initramfs. But now it's getting off the topic of this list, c...

...urd kernel is apparently connected to the extended syntax passed along to it by grub. Grub passes Hurd kernel approximately 4 files, some of which are modules, and another ten (or so) boot arguments, which correspond to those modules and kernel. The four files needed to boot the hurd kernel into an intramfs are apparently: 1) ld.so.1 2) initrd.gz 3) gnumach.gz and 4) ext2fs.static They are available at http://ftp.debian-ports.org/debian-cd/hurd-i386/current/ and the arguments to grub are as follows: multiboot /boot/kernel/gnumach.gz $options desktop=xfce module /boot/kernel/ext2fs.static ext2fs \...

On a train ride to Bruxelles, brought out my axe and directly attacked run_init(8). run_init(8) is dead, long live switch_root(8). The next run on switch_root(8) involves fdopendir, so another push for the upcoming stdio 1.6 branch. The following is boot tested with initramfs-tools, kinit(8) tests would very much be appreciated!? Michal Suchanek (1): [klibc] switch_root: Fix single file
