It isn’t being pedantic to call out this specific comparison as being unfair. You can still have your other examples.

This specific one (Green and Green) is what is being discussed. Don’t use worse examples when (allegedly) better ones exist.

Yes. Using kexec.

Though this is irrelevant for majority of users: I’ve never seen it as the default.

That +

WARNING: Use with caution! Kernel crashes, spontaneous reboots, and data loss may occur!

gives me the idea that its likely safer to just do a proper reboot, if your alternative is kernel patching or loading a completely different kernel.

Plus, its likely that not every single bit of firmware running on your devices support live patching. Thus you will be rebooting eventually, unless you are fine with avoiding the updates.

Generally no. There are some parts of your system that you will have to reboot for (like the kernel). But apps? Installing a new service?

No.

Most systems you just install the app you want, and run it.

There are some immutable distros the require things that are installed as part of the base system to only be available after a reboot, but they provide ways to install things without making it a part of the base system. Thus no reboot required.

Is what necessary?

I had to update a Chromebook-like machine that was running Windows not to long ago. It was excruciating. The restart progress bar on one update after reboot took ~30 minutes to reach 3%.

Keep in mind that the computer is unusable during this time, and all it takes is one poweroff to brick the machine. Ask me how I know :) . I had to leave it plugged in overnight to finish.

If this comment is referring to Windows reboots after update, I will call it confidently incorrect.

Discord servers are just groups. Lemmy “instances” are actual separate instances of Lemmy communicating.

They have also had this issue open for 20 years.

And this amounts to just allowing the user to specify a different directory for Firefox on Linux (~/.mozilla is terrible).

Frankly unacceptable.

Linus already has a backup. Its Greg Kroah-Hartman.

The data collected sounds like a nothing-burger. Of course they collect the data you upload, and of course they store data (like messages) that need to continue to be networked to clients.

How they use the data does sound like corporate trash though.
