Upgrading Jenkins to 1.454 from the command line on Mac OS X caused file permission changes.

[Jerome Lacoste]

Today I upgraded jenkins on the command line using:

    sudo installer -pkg jenkins-1.454.pkg -target /

This changed the permissions of the Jenkins home directory. I had to fix 
them using:

    chown -R jenkins:daemon /Users/Shared/Jenkins/

Is that a bug ? If not, what is the proper procedure to remotely upgrade 
jenkins on Mac OS X and not loose setup ?
