That is, if you'd use HOME=`dd if=/dev/urandom ...`.
If you have your users in /home/user, you can tell /home/*/.* is bad, /home/*/[^.]* is OK.
How would you exclude mozilla from writing to .* then? ".a" is bad, ".b" is bad ...? or "A" is OK, "a" is OK, "zzzzzzzzzzzzz" is OK"? Either way, you'd need several universes to store the security profile. -- The enemy diversion you have been ignoring will be the main attack.
