I think you'd have to go into more detail in describing this behavior.
Knowing setup.exe as I do, I'm guessing (and this is only a guess) that
you start setup on the system and manually specify the system root to be
the root of your unmounted filesystem instead of the default 'C:\cygwin'.
The old setup would first mount the filesystem, then go into /etc/setup on
that filesystem to extract installed package information, while the new
setup fails to do so.  You also do not provide any details about the
permissions of /etc/setup and the files in it on that filesystem with
respect to the users on the machine that's running setup.exe.

It would be great if you could reproduce this issue with a stock Cygwin
system after "umount -A" (which would allow setup developers to do
likewise).  If not, there must be more variables in play here.
