Absolutely. It's a part of the kernel I find very interesting. Here's a related bit from the kernel docs that describes the initramfs and switch_root in more detail. https://www.kernel.org/doc/Documentation/filesystems/ramfs-rootfs-initramfs.rst https://www.kernel.org/doc/Documentation/filesystems/ramfs-r... Interestingly, there's even a mechanism for leaving programs running even after exiting the initramfs.
