1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack members of the community for any reason.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.

    Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't fork-bomb your computer.

    See, this is why BTRFS is a good idea.

    I borked one of my installs today by accident. I'm not even sure what happened... I upgraded the kernel, then weird things started happening, then X just froze, I restarted, runit would't even go to phase 3 of the boot process, X couldn't load, just gave a bunch of errors. Oh well, BTRFS to the rescue ๐Ÿ˜Š. This is where things get interesting ๐Ÿ˜‚.

    I was on the phone with my wife while I was trying to bring back a snapshot of the volume... have no idea what I did, but I managed to wipe the root subvolume ๐Ÿ˜‚. Not like just empty, but completely gone ๐Ÿคฃ. OK ๐Ÿ˜ฌ. Let's see if the snapshots are still there. Yep, still there. OK, recreated the subvolume and tried to load a snapshot of it, this time, wuthout talking on my phone ๐Ÿ˜‚. Worked like a charm ๐Ÿ˜Š. Restart, sure enough, it loads grub and the OS, everything's back to normal ๐Ÿ˜Š.

    Start using filesystems that can make snapshots, like BTRFS or ZFS. Sure, they have a bit of a learning curve, but trust me, it's worth it.
