That requires us to notify to userspace, and this function does that by exec'ing one of the standard userspace programs. Given the trigger is received by the kernel in the first instance I don't know a better way of doing this. And if this is the best way, I don't think there is generic code in the kernel which does the same thing.well this isn't really different from the normal ctrl-alt-delete right? I would strongly suggest to follow the normal ctrl-alt-del path.. that follows the normal convention sysadmins are used to. It's not "/sbin/poweroff" fwiw... at least not hardcoded. Following the normal ctrl-alt-del codepath gets all the policy out of this kind of thing as well.. Hmm... that will work okay for reboot, where SIGINT to init is probably a better strategy than what we do now. But we'd still need something special for halt/shutdown. We followed the same principle for this as sparc64/kernel/power.c. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
