The instructions at
http://www.netbsd.org/Documentation/bootcd.html#macppcimage are
out of date with -current.

What is the current method for creating a macppc iso image?

BTW, I haven't been able to build -current for i386 or macppc in
over a week now. Anyone else having similar problems?

/usr/src/build.sh -r -U -u -m i386 -D /opt/build/i386 -O /opt/build/i386/obj -T /opt/build/i386/tools -R /opt/snapshot/i386 tools release

/usr/src/build.sh -r -U -u -m macppc -D /opt/build/macppc -O /opt/build/macppc/obj -T /opt/build/macppc/tools -R /opt/snapshotmac/macppc tools release
