set -e is always honored; -e on the #! line is only honored if the script is run as a regular executable, not explicitly with sh. Normally it makes no difference; the exception is if you run the test manually while debugging it. The reason why Lintian added a (pedantic) tag for this is that when you're debugging a postinst script and you run it with sh -x /var/lib/dpkg/info/foo.postinst, and then it doesn't exit on error, it's surprising and can be dangerous. It's an unusual situation, which is why it's only tagged with --pedantic. -- Russ Allbery ([email protected]) <http://www.eyrie.org/~eagle/> -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
