System: NetBSD 1.6 on SPARC

Machine: sparc
>Description:
	I attempted to install NetBSD 1.6 on an SS5/170 this evening.
	Everything worked until I got to /usr/mdec/binstall:

	assertion "size > 0" failed: file "/autobuild/netbsd-1-6/usr/usr.sbin/installboot/ffs.c", line 85, function "ffs_read_disk_block"

	and thus did the installation fail.

	I ftp'd the latest 1.6_STABLE from releng.netbsd.org, and tried again.
	Same error.

	I tried to repeat this on a stable, boring SS20.
	Same error.

	Our installboot is hosed. How did we release this way?
