Hi Harald, > We have already three types of shutdown: halt, reboot and > poweroff. All three are handled by the same restart action
Yep, and my original patch adds a forth to the same path the halt/reboot/poweroff. This is slightly different to the restart path: halt_reboot_pwoff() vs. restart_handler(). > and need what you call "dynamic reconfiguration". No, I was worried that registering a restart handler would affect normal reboot. But fortunately, that's not the case. > You may just pass required information via shared memory. You mean signals? Or am I looking at the wrong code? I think I see what you're saying with the restart handler, but it seems a little fragile: With the patch, we just to invoke `reboot -k`. Without the patch, we need to ensure that inittab has the correct restart handler, then SIGHUP init if inittab was modified, then SIGQUIT init to do the actual shutdown & kexec. Granted, systems that are expected to kexec can have inittab pre-configured with a restart handler that calls `kexec -e`, but this means that the kexec path depends on a specific configuration which isn't obvious.
