Just as a follow up to this thread, this weekend I installed 2009.06 and then ran ISC's minimization.ksh script and then image-update to the latest dev build - everything worked as expected.
Also, being the first time installing OpenSolaris, as opposed to SXCE, I have to say I'm impressed. At first I thought LiveCD was hokey. but the installation experience was clean. Also, I found that OpenBSD has better I/O than before, though I think this is more to do with the Xen upgrade. All in all, I'm pleased and glad I made the switch. The only thing that will make this better for me is for there to be a headless-install option, configuring stati and being able to install a minimized-OS directly (no need to run minimization script), but I assume these things will come soon now that SXCE no longer Thanks, Kent
