The mythical upgrade-without-reboot unicorn

[Steve28]

I keep seeing posts about people upgrading without reboots.  I sometimes think everyone is punking me.  Is this a thing?  How does one accomplish this?

Depends if the update needs a new kernel, not all updates do.

If you wait long enough to update you will likely never see reboot-free since updates are from installed to most recent available. As soon as there is a changelog that ships with a "src" change in the list that requires a reboot.

21.1 -> 21.1.1 reboot
21.1.1 -> 21.1.2 no reboot
21.1.2 -> 21.1.3 reboot

21.1 -> 21.1.3 reboot
21.1.1 -> 21.1.3 reboot
