To avoid having to reedit the file each time udisks gets updated, you should use the directory "/etc/polkit-1/localauthority.conf.d/". There you can place custom configs for polkit, that will be examined after the default config files have been evaluated.
To make it short:

Correct solutions are presented in the updated tutorial (see the first post).
