I then had duplicated this trigger 3 more times (I'll spare you), for java-1.4.2-sun, java-1.4.2-gcj-compat, and java-1.4.2-sun-devel. So all told about 200 lines to fix some PaX related flags with java. A clever soul will note that even I had figured out a better way to do it at the end when I wrote it. Except for some reason I just kept doing the same stupid routine 3 more times. Allow me to demonstrate by showing you what it looks like now:

# Java

%triggerin -- j2sdk java-1.4.2-sun java-1.4.2-gcj-compat java-1.4.2-sun-devel

killall -9 java >/dev/null 2>&1

if [ -d /usr/java ]; then

find /usr/java -name java -type f -exec chpax -emsrpx {} \; >/dev/null 2>&1

find /usr/java -name javac -type f -exec chpax -emsrpx {} \; >/dev/null 2>&1

fi

if [ -d /usr/lib/jvm ]; then

find /usr/lib/jvm -name java -type f -exec chpax -emsrpx {} \; >/dev/null 2>&1

find /usr/lib/jvm -name javac -type f -exec chpax -emsrpx {} \; >/dev/null 2>&1

fi

For anyone thats still bored enough to read down to the end of this thread, this is an example of an RPM trigger. The above detects (in one line!) when the packages j2sdk java-1.4.2-sun java-1.4.2-gcj-compa and java-1.4.2-sun-devel are installed/updated, and runs the following routine against them. Triggers make me happy.

You know the best part of all this was that the trigger right after this was a multi-package trigger that was the right way to do it all along. Staring at me.... mocking me....
