maniacs-setup script fails if home directory for {user} is not /home/{user}

[Rod Smith]

As stated -- for instance, if user "fred" has a home directory of /home/flintstone, the script fails with:

***************************************************************************
* Setting up SSH keys for fred
Generating public/private rsa key pair.
open /home/fred/.ssh/id_rsa failed: No such file or directory.
