- Then it's no more 'hardware independent' than anything else. You
- still have to rewrite the kernel code for the hardware that it sits
- on. Check out sometime just what the difference is between the time
- (say) USL ships the port kits and people start shipping product.
- You'll find that it's long enough to imply there's more than 'minor
- rewriting' involved.
-
- If it's so easy, where's Solaris for Intel platforms? How much work
- is NeXt doing to move their OS, which ought to move more easily than
- UNIX, since it is Mach-based and has a microkernel design (less to
- port)?
