Ok, i've read that guide and im worried about this:
"This procedure has worked for me with several external hard drives. You just need to make sure that the drive hosting your home directory is connected before you attempt to log in. If it isn't, you'll get an error -- which is preferable to the behavior of Tiger and earlier versions of OS X, which would create a new user folder and then change the home-directory path to that new folder, forcing you to reset the location again. (Unfortunately, Leopard client doesn't let you use this setting, alone, to place your home directory on a remote volume; for example, on an AirPort Disk.)"
Well, if i move my home folder to an internal disk obviously it IS connected while i attempt to login. So, i guess its not going to work?
