Moving user to a new home directory

This is a simple hack if you want to move an existing user's home directory to a new location. This is helpful if you have a new partition create for user's home dirs (e.g /home2)

1. Execute this 1 command

usermod -md /home2/bob bob
# /home2 must exist
# /home2/bob will be created automatically by the command
# bob's files on the old home dir will be moved to the new
# the old home dir (together with its contents) will be deleted

2. Test as root

su - bob
# this shouldn't return an error

3. You can also see that the /etc/passwd entry has been updated as well
grep bob /etc/passwd
