Hello Arch users,

I just upgraded to linux 4.0.1-1 in [core] from linux 4.0.0-2 in [testing]. In recent days, I've heard of lots of news that since kernel 4.0, no reboot is necessary for upgrading kernel. However, uname still gives me the old kernel version:

$ uname -r 4.0.0-2-ARCH

Is it necessary to run additional commands for completing kernel upgrading, or do I have to wait for some time? If I have to wait, how long should I wait for?

Thanks for any related information or opinions!

Best Regards,

Yen Chi Hsuan

If you're interested in something, you should really read the news instead of scanning the headlines. Live patching requires some work. Doug

According to my understanding, 4.0 just implements the groundwork required for rebootless patching of the kernel, there's still a lot of work to be done to implement this in the long run - specially for a desktop system. I wouldn't plan on seeing true no reboot patching of the kernel for a while yet.

Although, I do agree, I'm looking foward to that day!

Thanks a lot Dan, and it's obvious that I misunderstood something. I've looked into several technical or non-technical descriptions, but seen nothing about how to really activate the feature, such as commands or configuration files, but potential benefits from it. As a result, I think such a process takes place automatically without user intervention. After all, thanks all for the quick response! Best Regards, Yen Chi Hsuan
