Did you mean - set root login home to /toor? Or create a new toor user?

I think the same will be with .profile which also looks like it's 
hardlinked.

Wouldn't pkg already have to handle this for normal port packages 
somehow? Or they never create hardlinks? Is it worth raising bug/feature 
in bugzilla for pkg?
