Jamie, here's one topic I *do* have the answers for:
MacOSX is esentially the same thing as Rhapsody which is esentially the =
same thing as NeXTStep/OpenStep... they all have a Mach kernel, all have =
BSD Unix implementation. It's the higher level services and (graphical) =
user interface which differentiate between them.
As far as we know, even the "consumer-level" Mac OS X will have the =
ability (perhaps not by default but through an install option) to work via =
the unix command line - even over a telnet connection. Just like a real =
unix, because it is one.
Mac OS X Server is just a renamed Rhapsody Customer Release 1.0.
The big deal with Carbon - which is just a subset of the existing Mac OS =
API's plus a few new ones - is that developers will only have to modify a =
small portion of their existing applications in order to take advantage of =
protected memory and pre-emptive multitasking... which is what Copland was =
supposed to have delivered some years ago.
So we will have an OS which is unix at heart, with an advanced Mac OS GUI =
for those who like that, command line facilities for the more hands-on =
types, capable of running legacy Mac OS apps, updated "Carbon-based" apps, =
apps written to the updated NeXTStep API's (aka Yellow Box), 100% Java =
implementation, and last but not least the wealth of existing unix =
software through the BSD and POSIX implementation.
To keep this post somewhere near the FreeBSD list topic: seems like a =
knowledge of FreeBSD would give you a good foundation for running a Mac OS =
X box.
Regards,
Terry
