When the machine came up, it paused waiting for keyboard input. In one iteration, it released the hold after about 100 characters of quick typing. In another iteration, it waited as I slowly typed only a few characters a minute, until I gave up. In a third iteration, it waited indefinitely as I typed nothing, and I gave up after 5-10 minutes. In the first iteration, even after the system continued, various things complained and/or failed with a complaint of there being no /dev/random. named was one thing, but I know there were others. We've since moved on and picked up the post-revert sources. Scott
