Hi Xochitl,

Just to clarify, we are using Iceberg to create bundle install

packages for Installer.app.  The code I am writing is indeed in the

preflight script.

We have been able to fail the install just fine from the preflight

script by executing "exit 1".  But as you said, we have no way of

putting up a message to the user, though we emit useful messages to the log.

Thanks for the pointer to the UNIX domain sockets check code.  We

actually use that code in our daemon to set up the socket files.

But during install, we are trying to follow the recommendations in

TN 2083 for the daemon itself.  The questions I am bringing up

reflect problems our beta testers have encountered.

Thanks, Monte

It should be easy to create a volume check or installation check if you are using Iceberg.  With either of these checks you are able to present a meaningful message to the user.  If you make a preflight failure, the installer will fail, that is true.  I saw that in my testing also. Mr. Peelman has some good information about packages and how to make InstallationCheck give a nice error message. Or you could use a volume check to show that some volumes with bad permissions are not suitable destinations.  This is just one idea, of course, and it doesn't sound like it matches your preference, but there it is. Here I found the Apple link to my message that preflight is "not supported" (even though the failure "works"). It's from Mr. Bill Codere who's been commenting on your thread already, but he hasn't said this to you.  Maybe it is not true anymore?
