3) Unlike Linux, Solaris is a complete operating system. This means
that, yes, you can easily upgrade Linux because it is just a kernel,
fairly frequently without changing anything in userland except
drivers. Solaris, unlike Linux, is a complete operating system and
brings together many pieces to perform an integrated platform. Because
of this, you can't necessarily take a kernel from one version and plop
it into another and expect all of userland to magically work, though I
suspect it would work in many cases depending on the changes.
Actually, I would expect all of userland to magically work unless APIs
for system calls
are changed.
