Ah. No, it's not.
I'm guessing you hit that problem running in full emulation on an x86
host?
I've hit the same bug - we're actually getting an illegal instruction
during the execution of the postinstall scripts. Very odd. Obviously
a bug in TCG, but I haven't managed to track it down. It's not as
simple as an obscure instruction that wasn't implemented in TCG, it
appears to be a genuinely illegal instruction, which suggests guest
memory or register corruption. I haven't managed to track it down any
further than that, because of course being full emulation it takes
ages to get to that point in the install after each new bit of
instrumentation, and other bugs have taken priority.
