>Description:
I've attempted to install various versions of NetBSD/mac68k on my Quadra 650 with a SCSI2SD hard disc. Each time, I install using the NetBSD INSTALLSBC image using the BSD/mac68k booter.

NetBSD 8.1 successfully installed using sysinst by this method. The disc partitioning detected an 2GB SCSI disc with an Apple partition map with an 80MB HFS partition and the rest of the disc a free partition. It allowed me to create new swap and root&usr partitions and correctly newfs-ed the root&usr partition.

To install 9.0, I wrote /dev/zero to the entire disc, and recreated the 80MB partition.

NetBSD 9.0 RC1 and RC2 shows the same partitioning interface, but when I provide the same settings, it fails to re-partition the disc, and doesn't run newfs.
>How-To-Repeat:
1. Boot sysinst on a disk with no NetBSD root/usr partition.
2. Create swap and root/usr partitions
3. OK the partition creation step in the user interface.
4. newfs step doesn't occur, and package installation fails with an out of space error.
