Sad you included this misinformation in your otherwise good comment. Linux fundamentally works different and you can often update binaries as well as the kernel without rebooting.
And even if you couldn’t, that’s 100% a user problem. Every distro I’ve ever seen makes it clear as day when you do need to restart, so this is 100% a user issue. But I guess people will also complain if their OS forces them to reboot (like this post), so… 🤷🏼♂️
Linux can patch the executables on disk (as can Windows, with more trickery) while the system is running, but this still leaves the running processes in a vulnerable state.
The Linux kernel can be replaced on the fly, but this isn’t enabled on most distros. Even with it enabled, kpatch/livepatch isn’t a universal fix.
Replacing /usr/bin/firefox doesn’t fix anything if you don’t restart Firefox itself. The write lock on a running process isn’t what’s preventing Windows from being patched without a reboot.
On my box updating firefox and then restarting it won’t even launch the new version because NixOS knows I’m logged in and won’t just change things in my environment. But unless there’s a kernel update yes
nixos rebuild switchfollowed by logging out and logging in is equivalent to rebooting as it will automatically shut down and restart all system services, I think even systemd itself. Modulo some wibbles around kernel modules but those fall under kernel updates in my book.Contrast Ubuntu, which really likes to prompt your for reboots. The difference between a distro primarily for desktop use and one that can also do desktop because also devops want a desktop. Hey I could spin up 1000 cloud instances of my desktop with a couple of keystrokes isn’t that impressively useless :)
I don’t know what Windows needs to do to get as good of a state as Linux but you rarely need to do a full reboot as you seemingly are forced to do on Windows.
Just because your computer doesn’t tell you it needs to reboot doesn’t mean you don’t need to reboot to apply updates. It doesn’t take long for most processes in htop to show up as yellow, including the ones necessary to keep my desktop session and other system daemons running.
Maybe I’m the crazy one for not logging in/out more and not systemctl restarting everything every day, but I’m doing a lot more restarting on Linux than I ever need to do on Windows.
It does tell me. Zypper tells it outright and you’ll get a list with zypper ps -s. But like said, it’s very rare that you need to actually reboot. Restarting apps or services suffices.
Don’t know what’s up with that. With Windows it nagged about rebooting constantly. Seemingly every update. Meanwhile Linux can be just fine without, some stuff you need to restart but actual reboot is much rarer.
