When is a restart required

When is a restart required? Only with kernel updates? Not with systemd updates? I saw the kernel image for boot is updated when systemd gets updated.

Re: When is a restart required

Your question is not fully formed.  When is a restart required by/for what?  There is never any absolute need to restart.

You will need to reboot (or kexec) in order to start using a newly installed kernel, but the old one in memory will continue working indefinitely (though new modules wil not be able to load).

You could reboot in order to start using a new systemd/init.  But there are alternatives to rebooting for this too, and here also the old one in memory will continue working just fine.

I have an arch system that was last rebooted almost 5 months ago and has been running since.  And there wasn't really any need to reboot at that time.
