known problems with busybox 'init'

Well, the history is, until I combined the / root with the /usr, I
couldn't use busybox's init, as it was in /usr/bin, which wasn't mounted
or decompressed or unarchived when 'init' started.  Now, I can use busybox
init, so as of 2.0.48, I switched over.

But, it turns out, busybox init does not handle SIGHUP right, so, it is no
longer possible to change /etc/inittab from the rc.S rc.custom settings.s
places and reHUP it.

I dunno yet what I'm going to do about it, maybe enhance busybox init,
maybe go back to sysvinit, maybe find a different one.  For now I guess
just be aware of the problem.
