Ok, this is a easy :-)

Great! This helps me a lot!

I did not know /etc/setup/setup.rc, but it is there with the content:

last-cache
	C:\Users\admin\cygwin\.pkg-cache
mirrors-lst
	http://cygwin.mirror.constant.com/;cygwin.mirror.constant.com;United States;New Jersey
(...)        
last-mirror
	http://ftp.fau.de/cygwin/
net-method
	IE
last-action
	Download,Install

cygwin-portable-installer(*) is not an alternative package manager, but
just a script wrapper for setup.exe

The installation step is:

echo Running Cygwin setup...
"%CYGWIN_ROOT%\%CYGWIN_SETUP_EXE%" --no-admin ^
 --site %CYGWIN_MIRROR% %CYGWIN_PROXY% ^
 --root "%CYGWIN_ROOT%" ^
 --local-package-dir "%CYGWIN_ROOT%\.pkg-cache" ^
 --no-shortcuts ^
 --no-desktop ^
 --delete-orphans ^
 --upgrade-also ^
 --no-replaceonreboot ^
 --quiet-mode ^
 --packages dos2unix,wget,%CYGWIN_PACKAGES% || goto :fail


When I later run /setup-x86_64 without options it asks for 
"Choose A Download Source"

I can skip this step if I start it with:
/setup-x86_64 -s http://ftp.fau.de/cygwin

Is there something missing in my /etc/setup/setup.rc?
What should I add there?
Also the CYGWIN_ROOT (option -R)?

Ok, I could write a setup.cmd with the options you named, but it would be
better if setup-x86_64.exe knows my defaults.


(*) I need cygwin-portable-installer for my users, which are overcharged
with a regular cygwin installation. With cygwin-portable-installer I can
specify all needed packages, the installation place and some additional
software (of my own).
