The installer is compiled C code in 32bit vs 64bit, maybe if it was written in Java since Java does get loaded with the windowing layer and both 32bit and 64bit is supported in runtime with the same code base could be a answer. Also in the past there was a CD space issue in getting the kernel to boot with X-Window, Java and the installer ( ttinstall and GUI solaris-installer ) with support utilities on one boot CD and having both 64bit and 43bit would double the code to support with both 32bit and 64bit versions and adding extra 64bit binaries could have been a issue.. I am not sure about what is going on with the newer 2008.11 installer if is written in Java vs C, I have not looked at that closely yet also there is not a test (console) installer version yet ether.
I am not sure why 64bit is a issue other then a nice to have!, I thought for the main issue was the bugid's were fixed for flar flash files larger then 2g that were used for restoring system via Jumpstart rules profile option was resolved now? -- This message posted from opensolaris.org
