Command line options
The kernel will decompress the stream of compressed cpio archives passed to it by the 'append' bootloader option to the root of 'rootfs', a tmpfs automatically mounted at '/' by the kernel at boot.
Not to be confused with '/sbin/init', the '/init' script in the root of the 'rootfs' is called by the kernel upon completion of its boot process, and is responsible for doing whatever steps are necessary to mount the real root file system to '/' and transfer control to '/sbin/init'.
Minimal Required Set
- / /bin /boot /dev /etc /lib /lib/modules /media /media/cdrom /media/usb /mnt /proc /sbin /sys /usr /usr/bin /usr/sbin
- /dev (can be disabled?)
Feature sets consist of lists for the set of modules and files that need to be included in a final initramfs to support the indicated feature.
Not to be confused with the '/init' script in the initramfs, '/sbin/init' is the first process to be started in the live system after the initramfs completes its work.
