You can't use format(1m) for USB drives in Solaris 10 up to at least u8. I've never tried u9 because of the license change. I'd certainly agree about rmformat(1) however, format(1m) does not see flash drives even on OI 151a.
I see that format(1m) does see USB HDDs on OI 151a which is encouraging. For me that's a dual core Atom nettop I use for internet access only. That's not where I do serious work. It's where I evaluate OI and surf. I can live w/ failure on it.
When OI reaches the point I feel it is stable and robust enough to replace Solaris 10 u8 I'll transition the Z400 off Solaris 10. But for now I don't think we're there. Making progress to be sure. I've been very encouraged by your Sparc work. I very much prefer Sparc, but because I do heavy floating point work, I've been forced on to the x86 which I despise.
I never said anything about what you do. I have merely reported my experience. I've read your posts on your Sparc work w/ great interest, but I don't recall ever commenting about them.
As for "lots of moving parts" it's an American idiom for complexity.
