Actually, there are reasons why one might want to boot in single user
mode and mount / in read-write; when files in /etc get messed up
(fstab, resolv.conf, named.boot and namedb/* files, etc), when you
want to edit them, when you are going to install a new set of binary
after having built the world (though not required), or when you are
making a back-up (you don't want user processes fooling around with
the fs you're making the back-up), etc.
