One thing that is missing in this conversation is that you could be running this installer targeted at a volume other than the boot volume. It is really simple to catch this case, so we should always be pushing people to do this when they write installer scripts.

Good catch, and you're probably right about -w too. My reasoning was that if an upgrade fails, you don't want a half-broken install to launch until you have a successful install (which loads -w). So to summarize, the scripts should look like so: preinstall:

#!/bin/bash

LAUNCHD=/Library/LaunchDaemons/edu.caltech.autonomy.foo.plist if [ -e "$LAUNCHD" && "$3" == "/" ]; then launchctl unload "$LAUNCHD" fi

postinstall:

#!/bin/bash

if [ "$3" == "/" ]; then launchctl load /Library/LaunchDaemons/edu.caltech.autonomy.foo.plist fi
