This is honestly why anyone and everyone should invest in at least a small UPS that can keep your PC powered for at least five minutes so in this kind of scenario you can cancel the update, shut down safely, and resume when the power is back.

Or use a system that has rollbacks so you can use the last known good configuration

Btrfs snapshots + Timeshift that is configured to run pre-update is great for this, though I cannot remember if Fedora’s layout is compatible with Timeshift’s expected configuration.

OP, If you really want to go 100% with this, something like NixOS (which is definitely an extreme investment) or an Atomic distro like Fedora Silverblue works very well for this.

As you mentioned, with Fedora the best alternatives are immutable spins. Updating means downloading a new base image, applying overlays and additional installations to it and on the next reboot you start from that image. You can configure it to keep as many previous versions as you need and boot into those directly on startup. Since you never change your current image once it’s built, you can’t break a known good system. You can only ever break your next version and in that case, just boot the previous.

I’ve created an Ansible playbook that configures a vanilla Kinoite the way I want it. No need to back up the system if I can recreate it with less than a megabyte of text files. Secrets are in my password vault, personal files are in my personal cloud and get synced to and from the laptop continuously. I would never go back to backing up system files as opposed to recreating it with a playbook. That seems so wasteful in hindsight.

This is why my main personal machine will always be a laptop.

I have far too many networking appliances for that, myself.

Ideally yes, but using btrfs with something like timeshift is enough.

Any recommendations for a fairly cheap one? It would definitely come in handy.

Well for one, are we in the same country? US here. I’m not as savvy on pricings in the EU or anywhere else for that matter.

For two, it’s helpful to assume what you need is based on your PCs max wattage input imho. That way, if it can run your machine drawing max power (wattage) for 5 minutes, it can run it for longer when its drawing less power than that.

It was the least fun thing I bought for my pc but at least I can relax during bios updates. I got mine because there was some work being done on the house and I was always fearful that an electrician would turn off the power. I would never have a pc without one now.

It was the least fun thing I bought…

Knowing myself, I’d end up playing with it more than with the PC for the next 3 months trying it with the most random stuff. In the end I would probably have a spreadsheet with average and minimum power times with the most random stuff that doesn’t exceed its power limit. I am pretty sure it would also end up in my back pack for absolutely no reason at some point.

But of course, all of that only after watching every YouTube video about UPSs for 2 months prior to the purchase.

I like your thinking, I guess with Linux everything is a potential project (or two)!
