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 initramfs "image" I think this is not documented and I did not found it by gooling any comment will be greatly appre...

...king 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 the gunzip function to see what was happening. The core of the problem is in the init/initramfs.c, the populate_rootfs and unpack_to_rootfs functions. I see a 512byte image at &__initramfs_start being uncompressed. Then I see my image during the dry-run inside the "if (initrd_start)" block, which gets checked correctly with gunzip(). The problem is that the same call to unpack_to_rootfs() finds another header, which is...

...Do you not put them in your initramfs cpio? Why not? The only reason I see to have /dev is /dev/console, and the only reason for that is so that you can printk the warning that you could not open it. We mkdir and rmdir /proc and /sys, and even /old, so why is /root special? I'd like to move unpack_to_rootfs to userspace. Why? Because I'd like to have userspace be able to fetch cpios and unpack them, and if I have that in the initramfs, then that means I don't need a second copy in the kernel. I prototyped this idea back at 2.4.18 or so. Unpack includes a private copy of zlib, as does the i...
