But if it's no symlink but a mount you run into trouble, if you want to 
remount /var (e.g. because out of disk space).

So generally I would say this new directory you're looking for, should 
not be a subdirectory at all, especially if the parent directory is a 
frequently mounted one by itself. This would rule out /usr, /tmp, /var, 
/home at least.
So better go for the /new_directory variant, IMHO.
