[Users] Pxeboot - pwd/login issue

Mike,

ssh_pwauth=1 didn't work. The boot dropped into the dracut shell. I attached a snapshot so you can see the error.
BOOTIF worked. I could ping the node but ssh was rejected.

You can try booting with "BOOTIF=eth0 ssh_pwauth=1" in the command line.
This will configure networking and enable SSH password authentication.
Then you can ssh admin@<your host> and it will show you the error.

I'm using git://github.com/primalmotion/Node.git

The only differences I see between the 2 are some minor formatting and
conditional changes in recipe/Makefile.am and a couple patches that were
pushed since the github repo was updated.  These patches are all on the
gerrit.ovirt.org side.

Note:  there is an incompatible change that was merged into master this
morning.  I'm working on a rebase of the archipel stuff now to include
it.
