Re: Simplifying Cygwin PosgreSQL Installation

[Glenn Murray <gmurray at mines dot edu>]

Jason,

Thank you very much for your reply, I am learning a lot already.

Keep in mind that my goal is to simplify installation of Cygwin
PostreSQL, not to mention cygipc.  The difficult part of the install
is navigating through the setup.exe dialogs.  Your Suggestion #2
reproduces that problem and your Suggestion #3 makes it harder.  Only
your Suggestion #1 might simplify this by enabling me to tell the user
to "Hit the `Next' button until done", so let me ask about that.

By "Create a minimal Cygwin mirror" do you mean create a space on a
web server and put files (as described in
http://cygwin.com/setup.html) that setup.exe can find?  I did a search
in cygwin-apps for "upset" and found lots of references but not an
explanation.  I take it that upset helps build a setup.ini file which
gets downloaded from the mirror.  Where do you get it?  I didn't find
"upset" as a cygwin package.

How does setup.exe see this mirror and not the official Cygwin
mirrors, i.e., how do I "point my Windows users" to that particular
mirror?

Thanks again,
Glenn Murray
