Scott, this looks great!

It would appear you used merge-changelog to do the changelog. Apparently there are some entries out out of order, so merge-changelog moved a giant block of changes above version 20040623-2 that used to be below it. It also removed the erroneous, duplicate 0.52-2 entry.

I went ahead and restored the changelogs below the new entries to their original state.

Otherwise it looks good for sponsorship. Uploaded.

2819- This option causes busybox shells to use busybox applets
2820- in preference to executables in the PATH whenever possible. For
2821- example, entering the command 'ifconfig' into the shell would cause
2822- busybox to use the ifconfig busybox applet. Specifying the fully
2823- qualified executable name, such as '/sbin/ifconfig' will still
2824- execute the /sbin/ifconfig executable on the filesystem. This option
2825- is generally used when creating a statically linked version of busybox
2826- for use as a rescue shell, in the event that you screw up your system.

2871- one tries to use shell with stdin/stdout opened to /dev/console.
2872- This device is special - it cannot be a controlling tty.
2873-
2874- Proper solution is to use correct device instead of /dev/console.
2875-
2876- cttyhack provides "quick and dirty" solution to this problem.
2877- It analyzes stdin with various ioctls, trying to determine whether
2878- it is a /dev/ttyN or /dev/ttySN (virtual terminal or serial line).
2879- If it detects one, it closes stdin/out/err and reopens that device.
2880- Then it executes given program. Opening the device will make
2881- that device a controlling tty. This may require cttyhack
2882- to be a session leader.
2883-

2885-
2886- ::respawn:/bin/cttyhack /bin/sh

4797- *
4798- * For process with PID==1, on entry kernel sets all signals to SIG_DFL
4799- * and unmasks all signals. However, for process with PID==1,
4800- * default action (SIG_DFL) on any signal is to ignore it,
4801- * even for special signals SIGKILL and SIGCONT.
4802- * Also, any signal can be caught or blocked.
4803- * (but SIGSTOP is still handled specially, at least in 2.6.20)
4804- *
4805- * We install two kinds of handlers, "immediate" and "delayed".
4806- *
4807- * Immediate handlers execute at any time, even while, say, sysinit
4808- * is running.
4809- *
4810- * Delayed handlers just set a flag variable. The variable is checked
4811- * in the main loop and acted upon.
4812- *
4813- * halt/poweroff/reboot and restart have immediate handlers.
4814- * They only traverse linked list of struct action's, never modify it,
4815- * this should be safe to do even in signal handler. Also they
4816- * never return.
4817- *
4818- * SIGSTOP and SIGTSTP have immediate handlers. They just wait
4819- * for SIGCONT to happen.
4820- *
4821- * SIGHUP has a delayed handler, because modifying linked list
4822- * of struct action's from a signal handler while it is manipulated
4823- * by the program may be disastrous.
4824- *
4825- * Ctrl-Alt-Del has a delayed handler. Not a must, but allowing
4826- * it to happen even somewhere inside "sysinit" would be a bit awkward.
4827- *
4828- * There is a tiny probability that SIGHUP and Ctrl-Alt-Del will collide
4829- * and only one will be remembered and acted upon.
