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.

Tinkering is all fun and games, until it's 4 am, your vision is blurry, and thinking straight becomes a non-option, or perhaps you just get overly confident, type something and press enter before considering the consequences of the command you're about to execute... And then all you have is a kernel panic and one thought bouncing in your head: "damn, what did I expect to happen?".

Off the top of my head I remember 2 of those. Both happened a while ago, so I don't remember all the details, unfortunately.

For the warmup, removing PAM. I was trying to convert my artix install to a regular arch without reinstalling everything. Should be kinda simple: change repos, install systemd, uninstall dinit and it's units, profit. Yet after doing just that I was left with some PAM errors... So, I Rdd-ed libpam instead of just using --overwrite. Needless to say, I had to search for live usb yet again.

And the one at least I find quite funny. After about a year of using arch I was considering myself a confident enough user, and it so happened that I wanted to install smth that was packaged for debian. A reasonable person would, perhaps, write a pkgbuild that would unpack the .deb and install it's contents properly along with all the necessary dependencies. But not me, I installed dpkg. The package refused to either work or install complaining that the version of glibc was incorrect... So, I installed glibc from Debian's repos. After a few seconds my poor PC probably spent staring in disbelief at the sheer stupidity of the meatbag behind the keyboard, I was met with a reboot, a kernel panic, and a need to find another PC to flash an archiso to a flash drive ('cause ofc I didn't have one at the time).

Anyways, what are your stories?

Wanted a cool bootscreen on my Nixos machine - commented out the bootloader to troubleshoot, why my meme-boot-picture wouldn't show - after rebooting, it loaded straight into the BIOS and finally realized what I had done... Was able to fix it thankfully

Somehow I found ways to remove and break the GUI multiple times in multiple ways in multiple distros.

Different scenarios, different times, different issues trying to "fix". My usual fix after this was always to copy what I think I still had important and then move on with a reinstall.

Recently I have been playing with ZorinOS and broke it in the same way by fidgeting with pipewire. Distro hoped to Fedora Silverblue due to the immutable filesystem. I wonder if I will break this one in a way I cannot revert it easily with rpm-ostree. I almost feel challenged.

I deleted the entire taskbar.

I wanted to move my Arch VM to bare metal, so I copied out all the important bits. Then I wanted to move that copy to a new drive so I could boot into it.

I THOUGHT I'd MV all the files in the Arch install's etc directory using sudo MV /etc ...

I also (somehow) mashed my install's etc with Arch's and bungled both, with no live CD to help.

I learned a thing or two about absolute file paths...

Can't say I have any interesting stories. Most of mine are just the head-scratching "I don't know why that didn't work; guess I need to reinstall" kind of story. Like enabling encrypted LVM on install and suddenly nothing is visible to UEFI. Or trying to switch desktop environments using tasksel and now I have a blank screen on next reboot. That lame kind of stuff.

My coworker though... he was mindlessly copy/pasting commands and did the classic rm -rf $UNSETVARIABLE while in / and nuked months of migrated data on his newly built system. He hadn't even set up backups yet. Management was upset but lenient.

Renaming a mount point while mounted was a fun experience in losing data back in the big box Redhat 5.0 days.

Relied on an AUR package for building and signing my unified kernel image... one day it was outdated and geberating the image failed, I noticed that by the fact that the system refused to boot my OS. Fixing it was done in a few minutes but boy, that was a shock :D

Guess who also checks the exact output of the kernel rebuild now before rebooting!
