That's not the issue of the actual architecture, but mostly how Solaris
works. You usually cannot boot of a root disk made on one machine on another
one (unless you do -a and help it interactively), unless the machines are
mostly identical. In short, Solaris is not designed so that root disk can be
shited around. Linux is :)
