Community rules (click to expand)

1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
  • Don't get baited into back-and-forth insults. We are not animals.
  • 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.
  • 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, no politics, no trolling or ragebaiting.
  • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.
  • 5. πŸ‡¬πŸ‡§ Language/язык/Sprache
  • This is primarily an English-speaking community. πŸ‡¬πŸ‡§πŸ‡¦πŸ‡ΊπŸ‡ΊπŸ‡Έ
  • Comments written in other languages are allowed.
  • The substance of a post should be comprehensible for people who only speak English.
  • Titles and post bodies written in other languages will be allowed, but only as long as the above rule is observed.
  • 6. (NEW!) Regarding public figuresWe all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations.
  • Keep discussions polite and free of disparagement.
  • We are never in possession of all of the facts. Defamatory comments will not be tolerated.
  • Discussions that get too heated will be locked and offending comments removed.
  • Β 

    Please report posts and comments that break these rules!


    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 remove France.

    On my system, I can just run

    $ sudo systemctl reboot --firmware-setup
    

    And it'll take the system to the BIOS.

    From the systemctl(1) man page:

       --firmware-setup
           When used with the reboot, poweroff, or halt
           command, indicate to the system's firmware to
           reboot into the firmware setup interface for the
           next boot. Note that this functionality is not
           available on all systems.
    
           Added in version 220.
    
       --boot-loader-menu=timeout
           When used with the reboot, poweroff, or halt
           command, indicate to the system's boot loader to
           show the boot loader menu on the following boot.
           Takes a time value as parameter β€” indicating the
           menu timeout. Pass zero in order to disable the
           menu timeout. Note that not all boot loaders
           support this functionality.
    
           Added in version 242.

    But that requires me to boot into an os first. I do use it but if it's off then it feels redundant.

    Might still be useful for when you configured fast booting on your hardware. Stuff like that usually doesn't leave enough time for you to manually hit the hotkey during boot.

    Usually I just hold down the esc key when I start my PC. I have an nvme ssd in mine and it boots quick.

    Is there anything systemd can't do?!
