Yes, it's got some very fancy features. Basic functionality like being easily able to access the system console, and being able to operate for more than a few minutes without goofing up, or having documentation that is understandable, seem to be missing at this point.
The basic problem is that I can't get anything sensible out of the serial console. I can tip to the SP, and that works fine. But I just get junk output (if at all) on the console.
The KVM applet gadget is very nifty. And I can see output (once I've redirected to ttyb, anyway), but nothing I can do can persuade Solaris to accept keyboard input. It's just Solaris, as I can type into the GRUB screen OK. But if the install goes interactive I'm stuffed.
Anyway, I've got it installed by persuading it to jumpstart completely hands off. It insisted on asking for terminal type and locale before, although I'm not sure why. (Well, not completely - it complained about not being able to set the boot device and didn't reboot when it had finished installation, but that's OK, I can remote power-cycle it [and I've used that piece of functionality a few times today!].)
So my attempts here were to add:
to the add_install_client invocation, and make sure that terminal and locale were defined in the sysidcfg file, and then edit the menu.lst file to add install as a argument - after:
-v -m verbose install
Of course, I'm now stuck a little further on - looking at the kdmconfig screen where it's asking me to select an X server. Must find my notes about how to disable that prompt.
