Trying Fedora. Never rebooted so often in my life

Like the other comment mentioned, you don't need to reboot, unless you've updated the kernel.

If you somehow downloaded by mistake an immutable system, like Fedora Silverblue or Fedora Kinoite, know it's not the classic way to manage Linux systems.

But even with an immutable distro you don't have to reboot. The updated image just gets downloaded in the background and booted into when you restart. There is no harm in still being booted from the old image id you don't specifically need anything only included in the new one. Nothing forces you to reboot.
Silverblue is my daily driver. Everything is in flatpaks, which update automatically, or in distrobox which I have a bash script that updates automatically.
System updates download in the background and just boot automatically the next time you boot up. I just ignore them.

you should only need to reboot when updating the kernel. Why are you rebooting? Is it because the system is unresponsive?

I'm using the KDE version and updates come in automatically through Discover. They almost always announce in the system tray that a reboot is required.
- You also don't have to reboot when Discover says to. It's just saying that the updates won't take effect until you reboot. It could probably be worded better, for sure.
- sigh... i hate to say it but do your updates via command line because it will actually tell you if you need a reboot. As said above, it should only be for Kernel updates, and even then it will tell you that it will switch kernels next reboot and keep running on the current one.
  Most desktop applications for doing updates ask you to reboot not because its needed, but because they are being "safe" or not running with the same user rights as you are in the terminal.
- Do you have offline updates enabled in the Discover settings by any chance?

If you're using KDE, you can go to System Settings > Software Updates and

Set the notification frequency to weekly or monthly to reduce the number of update notifications.
Disable offline updates. This will install updates while you're using the system and you can choose to reboot when/if you want.

Opening Discover will check for updates and, if updates are found, show the tray notification regardless of your notification frequency and when you last updated.

Fedora does roll out updates pretty much daily, which can be annoying, but you can choose what and when to update.

Dude just change discover's update mechanism in the settings. Discover usually reboots to install updates so that nothing goes wrong. You can change it though, so that updates are applied instantly. That way you'll only need to reboot for kernel updates.

So after reading the comments it's not that you need to reboot. It's your need to process notifications.

Can you provide more details on why you were forced to reboot so regularly?

Fedora is nicest when you use a lot of flatpaks imo. They just update constantly in the background without reboot.

Only system updates need reboot.

Even better: Silverblue! (I use uBlue)
Everything gets updated in the background without even needing intervention, not even a "you need to click here to download and reboot to apply changes"-notification.
I shut down my PC every few days when I leave the house for longer and boot into the next base-image without even noticing.
And if I do because something doesn't work, I just select the image from yesterday.
Oh yeah, and 99% of my apps are Flatpaks anyway, which auto-update too by default.
I just don't notice my OS in any way, I just work with it. Lovely!
- I agree, I actually use Silverblue as well. The only thing I added was a script to auto update distrobox too.

Yeah, seems definetly excessive. I don't know fedora good enough to tell you what you're doing wrong though, sorry

I'm not doing anything wrong, it's just made that way. Browser update? Reboot. Update to an app that I haven't even opened in weeks? Reboot.
- It isn't, though. Made that way, I mean. I update maybe weekly and restart my system when I do. That's it. I seldom get notification that I need to update unless I open the Gnome Software app, and unless it's a security update, it's not imperative to do it just because it's there. And even then, it doesn't always require a restart.
  I've been using Fedora off and on (mostly on) for the better part of a decade, and I've never run into what you're describing. So no. It isn't "made that way." I imagine if it were, it would be a hell of a lot less popular.
- I am using Nobara, which is a Fedora based gaming distro. I definitely do not have to reboot for updates to software outside of system updates to the OS specifically. Updating Discord, Firefox, Steam, Heroic Launcher, Signal, etc does not require a reboot. Something sounds amiss. I am running straight Fedora on my Surface Pro and same story there, basically restart for system upgrades only.

Using MX Linux, I reboot only after kernel upgrade
