>Description:

http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/sparc/INSTALL.html
says:

  Fetch files needed to install NetBSD. Fetch a CD image,
  NetBSD-9.99.96-sparc.iso or the floppy disk images,
  sparc/install/floppy/disk1.gz and sparc/install/floppy/disk2.

but http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/latest/sparc/
doesn't contain an "install" subdirectory.  There is a directory
called "installation", but it doesn't contain any floppies.

>How-To-Repeat:

Read the instructions.
