I was just pointing out the fact. The fact that noacl is perfectly valid is something we package maintainers have to keep in mind when creating postinstall scripts.

Is there a proper way for a postinstall script to find out whether it's an install for all users or Just Me? Hmm, afaik no. You could try to write to All Users first and if that fails, write to the user's own Programs. Sounds like the way to go (for the moment anyway), especially now that mkshortcut correctly reports success. But, maybe we should define a couple of useful, installation-specific arguments for postinstall scripts and change setup accordingly? I think that would be useful. Looking at the source in script.cc, the Cygwin root is passed as a variable already. I should have started by saying that, as a practical matter, this is not a problem for me. I have a minty shortcut and renaming /etc/postinstall/minty.sh to /etc/postinstall/minty.sh.done stops the error message from coming up. Yep, that's the right workaround. And thanks for this upgrade of setup. For some time now the pending view had the same two empty packages appear each time I ran setup. Very annoying. Now, they no longer show up. Dave Korn fixed that one. A relief indeed.

No, but I don't think it would hurt to enhance setup.exe, either by adding arguments to postinstall/preremove scripts, or by adding an environment variable like $CYGWIN_AUDIENCE with the values all_user or just_me.
