How to remove '/home' directory?
Open the following files with read/write permissions:

/etc/auto_home
/etc/auto_master


These files are part of the autofs installation. 

In the auto_home file, add a # before the + on the following line:


  +auto_home # Use directory service


In the auto_master file, add a # before the /home on the following line:


  /home          auto_home   -nobrowse,hidefromfinder


Save both files, and reboot your computer. /home should be free to work with. 

To reverse the changes, undo what you've done to both auto_master and auto_home.
