but the fact that the most promising part of the software (cluster administration) didn't work at all was a big disappointment. There are so many

mistakes in the software provided, that I can't believe anyone tested this before releasing it. Correcting all the errors and missing parts takes more time than configuring things by hand. I would have expected to find a new, corrected CD-image for downloading by now.

The Kickstart part is fine but needs quite a bit of additional information (you don't need a 4GB HD and you don't have to install software packages you don't need). Not exactly the quality I expect from your company !
