I tried replacing this block with struct names as specified in https://www.kernel.org/doc/Documentation/x86/boot.txt: struct boot_params * base = (struct boot_params*) loaded_image->ImageBase; base->hdr.ramdisk_image = (uint32_t)(uintptr_t) initrd_buffer; base->hdr.ramdisk_size = (...

As we can see,initramfshas an/etc/fstabfile that is empty. Another way to verify its existence is to use thelsinitramfscommand for the specifiedinitramfsarchive: $ lsinitramfs /boot/initrd.img-5.4.0-144-generic | grep fstab etc/fstab ...
When multiple directories and files are specified then the initramfs image will be the aggregate of all of them. See <file:Documentation/early-userspace/README> for more details. If you are not sure, leave it blank. In short, you can build (another) cpio-format image file that represents...
If we can be a little sloppy for a minute or two, both of those concepts refer to a simple idea — that of an “early userspace” root filesystem that can be used to get at least the minimum functionality loaded in order to let the boot process continue. There’s a lengthy explanati...
The root filesystem used by the kernel is specified by the boot loader as always. The traditionalroot=/dev/sda1style device specification is allowed. If a label is used, as inroot=LABEL=rootPartthe initrd will search all available devices for a filesystem with the appropriate label, and mo...
