The command 'nodeaddunmged' should not the proper way for you to add an
unmanaged nodes.
I do think that after adding the existed node to xCAT, you want to make the
node has the capability to power on/off, to run xdsh command ...
The correct way will be:
1. Add the correct definition for the node by 'mkdef'.
2. Run 'updatenode -k' to set up the no-password access from MN to CN
3. Run 'updatenode' to run postscript for the CN to finish the setup.
Thanks

Hrmm, on further thought I realized that replacing the makedns command
would probably be insufficient since there is no reason for xCATd to
call the external command when all that does is call back to xCATd, and
sure enough, testing shows that doing so has no effect on the hang.
The dns functionality does not appear to be required to succeed by xCAT
to consider the nodeaddunmged command successful since nodeaddunmged
does eventually return, but it's awfully annoying to have to wait
several minutes every time you call nodeaddunmged.
