Comment 5 for bug 1087679

I've been testing with an alternate config file that changes the user to 'oem' instead of 'utah'. The first thing I found with this is that the sshprivatekey defaults to the oem user's home directory, so I had to change that to point to the utah user in the same config file. After that, I realized the uploadfiles method of the SSHMixin class doesn't specify a username, so all files are uploaded as the user running the script, in this case, utah. This fails when there is no utah user, but confusingly throws this exception:
paramiko.SSHException: not a valid DSA private key file
I'm going to test a utah code change to see if that in conjunction with the updated config file and the preseed changes will fix this.
