Rather than altering chown, or invoking widespread changes to your filesystem, you could make a chown function which you put in root's ~/.profile or equivalent:

Code:
chown() {

        # Get rid of switches
        while [ "${1:0:1}" = "-" ]
        do
                OPTIONS="$OPTIONS $1"
                shift
        done

        for FILE in "$@"
        do
                set -- `ls -l "$FILE"`
                if [ "$3" = "root" ]
                then
                        echo "ERROR altering file/folder owned by root"
                        return 1
                fi
        done

        echo /usr/bin/chown $OPTIONS "$@"
}

Remove the 'echo' once you've tested and are sure you want. And be careful testing it in case you call the real chown by accident! Run it on something harmless.

This won't catch everything modified by a chown -R.

bcron-update(8) 					      System Manager's Manual						   bcron-update(8)

NAME
bcron-update - Update system crontabs. SYNOPSIS
bcron-update path [ path ... ] DESCRIPTION
bcron-update polls the named files or directories periodically to see if there are any new, changed, or removed files. When it detects changes, it mirrors those changes into the crontab spool directory. bcron-update runs as root in order to be able to read system files that would potentially be unreadable otherwise. On Debian, if path is a directory, bcron-update skips files in this directory with names that do not solely consist of lower- and uppercase letters ('a'-'z', 'A'-'Z'), digits ('0'-'9'), underscores ('_'), and hyphens ('-'). EXAMPLES
To mirror modern vixie-cron's behavior, use: bcron-update /etc/crontab /etc/cron.d ENVIRONMENT
BCRON_SPOOL The spool directory for bcron. Defaults to /var/spool/cron. BCRON_USER After writing files and before moving them into their final location, bcron-update changes the ownership of the file to this user so that bcron-sched can read them. SEE ALSO
bcron-sched(8) DIAGNOSTICS
bcron-update outputs three different kinds of messages about actions it is taking. Rescanning /etc/cron.d The named directory has been modified, and will be scanned to determine what files have been added or deleted. -/etc/cron.d/oldfile The named file no longer exists and will be removed from the spool. +/etc/cron.d/newfile The named file was either created or modified since the last scan, and will be copied into the spool.
