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.

Hehe... I installed Gentoo last year and I was thrown in the deepest of deep ends after having to set up a custom initramfs for my LUKS setup... took about a week to get it running...
I created a bash script which creates a custom initramfs for me every time kernel is updated. 😜 I know, I reinvented the wheel... kinda. My script actually only takes a list of files, directories, modules, firmware files and packs them into a cpio archive. The actual init scripts inside initramfs (for example) are not provided, but left for the user to write or copy from somewhere.
I was too lazy to actually learn dracut, and I thought that setting up custom initramfs would help me gain insight into the linux boot process. Normal Gentoo stuff lol
