1) Does NetBSD REQUIRE a swap partition?

2) What's the state of Apple UFS support in NetBSD-2.0 and/or later?  
I'm trying to use NetBSD-2.0, and I'd like to keep doing that, as 
binaries are available...

Here's why I ask...

I have a disk with NetBSD-2.0 installed on a Apple UFS partition.  From 
OpenFirmware, I can load the NetBSD kernel from this UFS partition with 
the following sequence:

	boot hd:,\ofwboot.xcf

	<blah blah complaint>
	open /netbsd: No such file or directory
	open /netbsd.gz: No such file or directory
	open /netbsd.macppc: No such file or directory
	Boot:

I then enter:

	hd:10,/netbsd

and the NetBSD kernel loads.

Unfortunately, at the end of the process, I get stuck with the 
following repeating sequence:

	cannot mount root, error = 69
	root device (default wd0a)
	dump device (default wd0b)
	file system (default generic)
	no file system for wd0 (dev = 0xa00 )
	cannot mount root, error = 69
	root device (default wd0a)
	dump device (default wd0b)
	file system (default generic)
	no file system for wd0 (dev = 0xa00 )
	cannot mount root, error = 69
	root device (default wd0a)
	dump device (default wd0b)
	file system (default generic)
	no file system for wd0 (dev = 0xa00 )

I don't know what it's doing here.

Here's some more pieces of information, if they're helpful.  If I boot 
from the NetBSD-2.0 CD, I can run the following:

	#disklabel wd0
	disklabel: Invalid signature in mbr record 0

Now, there are a few things I can think of that I need to see about 
resolving.

I suspect that at least part of the problem is that the "flags" and 
mount point information isn't set -- "sysinst" has asked me for this 
information in the past, but I can't find a way to edit it (I thought 
pdisk would do that, but I can't seem to get pdisk to give me the 
option of changing flags on a partition).

Is it possible to boot from an Apple UFS partition, without a swap 
partition?  Can this be made to work?
