Verified. I ran three separate tests ("virgin" installs), all from a
machine on which %HOME% was set to a network share that contained
pre-existing (noisy) .dotfiles.  In each case, the installation was
performed from a local rsync mirror of release-2, modified by the
inclusion of my special "fake" package, which:
  1) has an /etc/postinstall/ script to print out some diagnostic info
(labelled "inner" in the transcripts below), and
  2) has a very large list of requires: for my preferred initial
installation.


****************
1) The original setup 2.625, but with Sciprt::run() modified to print
out Eric's requested information from the "outer" /usr/bin/bash.  This
failed in the expected and previously-reported manner. In addition to
the partial transcript below, the resulting installation was thoroughly
broken. None of the alternatives-derived symlinks were correct; random
files ended up in / for some reason. Very bad.

2) The "corrected" setup 2.625, where rather than reporting that bash is
invoked with --norc --noprofile but then invoking it without those
flags, this version actually uses those flags in the invocation. Also
"instrumented" as above. This worked as desired as shown below, and by
the fact that the installation was fully functional and correct, as far
as I could tell.

3) The "corrected" setup 2.625, as checked in to CVS (that is, without
all the extra instrumentation).  This also worked as desired.

I've placed all three logs here (because even compressed, it's 700K):
http://cygwin.cwilson.fastmail.fm/ITP/setup-logs.tar.bz2
in case anyone is interested, but that link will go stale in about a week.

Whoever's in charge of making new setup-1.7 uploads...can we get an
update?  I'm not sure how the serial/version number is updated; all of
my builds reported the same 2.625 number -- so whatever magic happens to
bump that to 2.626 needs to happen, too.
