Recent kernels have support for populating a ramdisk from a compressed cpio archive. On such systems, the creation of a ramdisk image doesn’t need to involve special block devices or loopbacks; you merely create a directory on disk with the desired initrd content, cd to …

The kernel build process can also build an early userspace image from source parts rather than supplying a cpio archive. This method provides a way to create images with root-owned files even though the image was built by an unprivileged user. The image is specified as one or more sources in CONFIG_INITRAMFS_SOURCE.

What is this about¶. If the ACPI_TABLE_UPGRADE compile option is true, it is possible to upgrade the ACPI execution environment that is defined by the ACPI tables via upgrading the ACPI tables provided by the BIOS with an instrumented, modified, more recent version one, or installing brand new ACPI tables.

For the Linux kernel to support the initial RAM disk, the kernel must be compiled with the CONFIG_BLK_DEV_RAM and CONFIG_BLK_DEV_INITRD options. Testing the custom initial RAM disk Your new initrd image is in /boot, so the next step is to test it with your default kernel. You can now restart your Linux system.

- Extend CPIO header to support xattrs. This seem to be the most straight forward way. It also allows to do other useful changes to CPIO format at the same time. E.g. increase filesize field to support files >4GB. This patch set extends the existing newc CPIO archive format to include xattrs in the initramfs.

Jul 28, 2018 · The first is to link the cpio archive with the kernel by specifying CONFIG_INITRAMFS_SOURCE, which you leave null. The alternative is to pass the address of the cpio archive in place of the initrd image during the kernel start. U-Boot passes this address to an ARM kernel using an ATAG. – sawdust May 23 '18 at 21:13.

Sep 30, 2009 · This week, I’m not going to write a formal column so much as just free associate a bit regarding an exchange we had recently on the Kernel Newbies mailing list regarding the ideas of initrd and initramfs, and what they’re for and, most importantly, how they differ. And that’s where we might get deliberately vague […]Author: Rob Day

Creating the .cpio and .igz. When passing an initramfs to the kernel using your bootloader (the initrd option in Grub), the kernel is expecting a gzipped cpio archive (.igz). When building the initramfs image into the kernel, one of the easiest ways is to create a cpio archive (.cpio). We will be creating both files. $ …

All variants of Unix also support other backup and archiving programs, such as tar, which has become more widely recognized. The use of cpio by the RPM Package Manager, in the initramfs program of Linux kernel 2.6, and in Apple's Installer (pax) make cpio an important archiving tool.Developer(s): AT&T Bell Laboratories
