what happens when you someone logs in from a different computer... it doesn't actually mount /export/home .. it loopback/nfs mounts /export/home/username so you can have 100's of users from 100's of servers. another case where automounter makes sense these days is when you are using zones. you can share your home directory to non-global zones. and they only see one user.. not all users home directory.. and only when the user is logged in.. so its a security protection.
