Well I believe I've reached the bottom of one problem. It appears that when kicked off through a preseed install, DEBCONF_REDIR and file descriptor 3 (hereafter FD3) are set.
These are set all the way down the stack upto and including apt-get. However when apt-get runs dpkg-preconfigure, FD3 is no where to be seen. I put a "sleep" right at the top of dpkg-preconfigure and I still couldn't see it - so I'm fairly sure that apt-get is not passing FD3 though. As a gross hack workaround (which might break god knows what else) I've edited /usr/share/debconf/confmodule to unset DEBCONF_REDIR if /proc/$$/fd/3 does not exist. I now no longer get the confmodule line 42: 3: Bad file descriptor error messages :-) However, I still get some hangs (one I've seen before). In this case, dpkg-preconfigure is sat in a waitpid(pidof /tmp/postfix.config...) whilst postfix.config is sat reading STDIN (which is FD#8 from the dpkg-preconfigure. There is a dpkg-preconfigure zombie process between these two.
