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.

In Fedora, and other distros using Systemd, potentially in some distros that don't use Systemd as well, using tools like dracut or mkinitcpio you can enroll TPM2 to Secure Boot and seal TPM to NOT request LUKS password every boot.
