Other than the kernel (and probably some firmware?), what updates require a reboot these days?

Other than the kernel (and probably some firmware?), what updates require a reboot these days?
- CraigJPerry 2y agoIt’s not because the reboot requires it (even kernel can be kexec(1) in place for the last 10 years or so). It’s because your system state is mutable[1] (and so you don’t know if it’s capable of coming back up). 1 - There are distributions where this isn’t the case, but it is for the majority.
- yjftsjthsd-h 2y agoI mean, kexec effectively is a reboot, it just plays with the implementation to skip hardware initialization.
