Perhaps it might be reasonable to try to find a way for accounts like
msql and www-data not to be able to access home directories (add
"daemon" to their supplementary group list and set the permissions of
/home 0705 to root.daemon, perhaps), but is this really worthwhile ?
If it is, the right thing to do is to go away and think about exactly
