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.

    1. have an nvidia GPU

    2. have Fedora

    3. download RPM package of drivers for Red Hat (after all, Fedora and Red Hat are… compatible, right?)

    4. Everything goes fine

    5. Six months later, upgrade to a new version of Fedora

    6. oops, kernel panic at boot after the upgrade, and no video to troubleshoot after UEFI boot

    7. figure out how to boot into a recovery partition from UEFI

    8. figure out how to enable a serial console over a USB device

    9. figure out how to connect to the serial console from another computer using another USB device

    10. figure out what the kernel panic is from (not the upgrade, but the driver which wasn’t upgraded)

    11. figure out how to uninstall the incorrectly installed driver

    12. figure out how to install the correct driver

    That was a fun three week OS upgrade.
