From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Hello, what are the differences? As i understand efistub is loading straight to kernel and uki is file which connects initramfs ucode and kernel, but whilei create efistub i give parameters for initramfs and ucode so i dont understand why uki would be better? Also what would be better for encryption with esp partition or without?

UKIs are good for secureboot/measureboot, because you can sign the uki, and everything inside of it be validated for secureboot. If you really like to have a secure chain without a uki, you need to validate all the boot components. You can do it with grub and gpg signatures, but is more simple to use an uki and a efi bootloader like systemd-boot
