Linux needs to grow. Stop telling people it's 'tech-y' or acting like you're more advanced for using it, you are scaring away people. Linux Mint can be used by a senile person perfectly.
Explain shortly the benefits, 'faster, more secure, easier to use, main choices of professionals and free'. Ask questions that let you know if they need to dual boot, 'do you use Adobe, anti-cheat games, or Microsoft Office', 'how new is your computer', 'do you use a Mac'.
And most importantly, offer to help them install.
They don't understand the concept of distros, just suggest Linux Mint LTS Cinnamon unless they're curious.
That's it, spread Linux to as many people as possible. The larger the marketshare, the better support we ALL get. We can fight enshittification. Take the time to spread it but don't force it on anyone.
AND STOP SCARING PEOPLE AWAY. Linux has no advertising money, it's up to us.
Offer family members or friends your help or copy and paste the below
how to install linux: 1) copy down your windows product key 2) backup your files to a harddrive 3) install the linux mint cinnamon iso from the linux mint website 4) use etcher (download from its website) to put the iso on a usb flash drive 5) go into bios 6) boot from the usb 7) erase the storage and install 8) press update all in the update manager 9) celebrate. it takes 15 minutes.
edit: LET ME RE-STATE, DO NOT FORCE IT ON ANYONE.
and if someone is at the level of ignorance (not in a derogatory fashion) that they dont know what a file even is genuinely dont bother unless theyre your parents cause youll be tech support for their 'how do i install the internet' questions.
So when it comes to kernel modifications, I'm old school...
"If it's not broken, don't fix it." :)

Unless there's some VERY specific need, some security hole that needs patching, some critical flaw that is failing, in general, DO NOT mess with the kernel.
That being said, there are tons of good guides you can find just by googling "linux kernel modifications", but also specific guides for your installations. RedHat makes it dead simple to do stuff like this.
But before you do it:
Make sure you have a specific need you're addressing.
Make sure you have all the necessary backups you require.
Have a roll back process in case something goes wrong.
Have a diagnostic testing plan.
what I actually need is understanding the kernel.
At least process, memory management, ipc, handling device, etc.. Reading "The design and implementation of the 4.4BSD operating system", but I think I need to read something before reading that book.
