in 10.4.7 (from an admin login), all I did was click "get info" for the boot drive, then unlocked the prefs.. gave myself ownership (it was set to "system") and that was it.. set the view options to what I wanted for the boot drive, then restarted the Mac.. Went back and checked random folders, and every folder was set to my new prefs.. No clue how long that will last, but at least it works for now..
