    The power is out and my laptop has less than 10% battery left?

    It's pacman -Syu time.

    [–] [email protected] 66 points 3 months ago (1 children)

    Exactly my thoughts as well.

    Why update on that little battery life left... the power will return sooner or later, going without updates even for a week or two is no real problem. Hell, I update like once every 3 weeks to a month, it's not that big of a deal.

    [–] [email protected] 4 points 3 months ago

    I update always after a session, meaning about once a month 😂I don’t really need my PC, lol

    Wait if the power is out, how do they have Internet to load new packages? Something doesn't make sense here

    It first downloads all packages from net, then it proceed totally offline starting by verifying downloaded files, signatures, extracting new packages and finally rebuilding initramfs.

    Because arch is replacing the kernel and inittamfs in-place there is a chance that it will not boot if interrupted.

    This issue was long resolved on other distro.

    One way to mitigate it is by having multiple kernels (like LTS or hardened) that you can always pick in grub if the main one fail.

    This issue was solved on Slackware in 1993.
    It installs a "huge" kernel that contains all drivers to run on almost any hardware by default, alongside the "generic" kernel with only the modules you need. If the generic kernel fails to boot, you always have the backup, which is known to work, cause it's the kernel you first boot into after installation.

    I'm not familiar with slackware but why is specific kernel called generic, while generic one is not called generic? I'm puzzled

    [–] [email protected] 3 points 3 months ago* (last edited 3 months ago)

    I have no idea either.

    Edit: Did some reading. "Linux-generic" is just the name of the linux kernel that is used in most computers (as opposed to Linux-realtime, which is the only other Linux kernel that's still relevant).

    Yeah but how can you download without internet

    [–] kolorafa 1 points 3 months ago* (last edited 3 months ago)

    (No internet =} no download = no failure

    You can even host repo mirror locally, that will still work without internet ;)

    How to have internet without power?

    • Mobile hotspot
    • Router and AP using UPS
    [–] [email protected] 11 points 3 months ago (1 children)

    Cable internet tends to stay online even if your power is out. You'd need a battery backup for your modem/router, but it is possible to stay online. Houses can be clever like that, almost all of your utilities will partially work, even when service is interrupted.

    [–] [email protected] 7 points 3 months ago

    That depends on the ISP having backup batteries for their equipment. It will usually only last a couple of hours. 5G will usually stay up for a few days. For longer outages, you will need satellite internet and lots of fuel for your generator.

    Cellular data

    [–] devfuuu 2 points 3 months ago (1 children)

    My router has a 5G backup connection and a battery. Light could be out and I'd still have internet. So, yeah, it's possible :P

    [–] [email protected] 1 points 3 months ago* (last edited 3 months ago) (1 children)

    But if the power goes out isn't the stuff from your ISP/mobile carrier out too?

    [–] [email protected] 3 points 3 months ago

    Nah, cell towers often have some kind of backup power good for a couple hours or more, at least in the city where I am. I think I once had an outage last 3 days when a tornado wrecked the local transformer station, and still had cell service the entire time.

    I don't think I've had a pacman update take longer than 10 minutes before. Sounds like OP was updating all their AUR packages too.

    Still absolutely a terrible thing to do on 10% battery life. I bet there's an AUR package for "check battery level before update" out there somewhere though.

    OPs meme is "use distro whose model is 'give users enough rope to hang themselves' " and complaining he's at the gallows

    [–] [email protected] 1 points 3 months ago

    I imagine being at the gallows sucks even if you know why you are standing there

    [–] kolorafa 1 points 3 months ago

    What about a desktop PC?
