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.

I'm working on a some materials for a class wherein I'll be teaching some young, wide-eyed Windows nerds about Linux and we're including a section we're calling "foot guns". Basically it's ways you might shoot yourself in the foot while meddling with your newfound Linux powers.

I've got the usual forgetting the . in lines like this:

$ rm -rf ./bin

As well as a bunch of other fun stories like that one time I mounted my Linux home folder into my Windows machine, forgot I did that, then deleted a parent folder.

You know, the war stories.

Tell me yours. I wanna share your mistakes so that they can learn from them.

Fun (?) side note: somehow, my entire ${HOME}/projects folder has been deleted like... just now, and I have no idea how it happened. I may have a terrible new story to add if I figure it out.

I once just uninstalled sudo and replaced it with doas. Turns out, the shutdown process needs sudo and a lot more. So I am still using my system since then, without shutting down.

No joking, I use Fedora Atomic and can not break my system... unless you mess up your dotfiles, and a lot more.

I also put a drive into my /etc/fstab once without the nofail argument.

No idea why that is not set by default, but when removing that drive my system couldnt boot and I exited to a very scary dracut shell.
