Frankly I couldn’t imagine a worse idea to fix this problem. Many daemons will corrupt their state if they aren’t killed cleanly. Leaving them a grace time is actually worse than simply cutting the power, because you can be sure the daemon is actually writing some data at the moment you kill it. The most funny thing comes from daemons which depend on each other. You will easily hit cases where a daemon will not shut down properly because it cannot find the one that depends on it, and in the end increase the shutdown time instead of shortening it. Let’s just switch to a parallel init system, and the Ubuntu wannabees will win their precious few seconds without risking to introduce data corruption bugs on production systems. -- .''`. : :' : We are debian.org.
