You must maintain backwards compatibility with the OpenBoot environment. We just sent back an order of X4100s because the Jumpstart installation process was full of bugs and incompatible with our painstakingly developed over many years Jumpstart-over-serial-port infrastructure. (We could have used the ILOM's console to worksround this but we found it buggy and it hung on us several times, requiring power cycles.) We returned the X4100s and reluctantly bought V210s.
The differences in the Jumpstart process were largely undocumented, or at best poorly documented, and simply did not have two or three weeks to find wordarounds for the bugs on my own. (I posted several detail to the old sunforum.sun.com forums but all posts to that site seems to have been lost in the Forum reorganization. Things like references to nonexistent Appendices in documents, the confusing Solaris DHCP server, etc.) Basically, the "delta" to transition to any completely new installation paradigm has to be lower than the "delta" to just transition to some other OS. Developers can code on any OS, the only differences between OSes we care about have to do with installation, maintenance, and disaster recovery. Tread carefully.
