Can Darwin boot on a diskless system?
What do you mean by disk? The OS has to be read from something and it
doesn't have to be a "disk" in the traditional sense of the word.
Hard disk, CD, DVD, ZIP, etc.
Networking booting of Mac OS X is supported see...

I've heard of netbooting but I don't know any details. Is nothing loaded
from a local disk? That is, does firmware make a network connection and
download the needed files? Does a netbooted machine still need a local
writable disk? Can VM work over a network? Does Darwin need to have swap
file(s)? If RAM is large enough, can everything happen over the network?
Can Darwin continue to operate on a system where the disk(s) have
become unavailable (gone offline, crashed, etc.)?
If the "disk" that contains the OS image and more importantly the VM
swap space goes away the system will most likely fail soon afterwards.
That is the answer I was expecting. I just want to know how robust or
fail-safe Darwin is.
What do you want to do and how does it not require some type of "disk"
to function.
I'm mostly seeking knowledge. If Darwin can startup and run without a
disk, then the whole Mac OS is closer to being able to do the same, then
it might be useful to write Mac software that is "diskless friendly".
I guess a better, more general question might be, "Can Darwin startup
and run without a writable disk, local or remote?"
Does any of this make sense to you or just to me?
Thanks,
Bernie
