Hello mates,

As you know, in arch Linux the kernel is updated frequently but, is mandatory or good practice reboot any time the kernel is updated?

Edit: Thank you guys for your replies

    I’ve heard about Linux servers running for years. But surely they change kernel without a reboot? More of a curious question.

      there is live kernel patching, most distros (like Arch Linux) however don’t set this up by default
      there is also the possibility that one live patch don’t work properly
      the only reliable way currently to load the full new kernel is via reboot

      the real way for server however is to not rely on one single server but have a redundant amount which you can reboot one at a time

        Last time I tried replacing the kernel without a reboot it still reset the uptime. And it had about as long of a pause when replacing the kernel as a reboot had. So I don’t see the benefit.
