System: NetBSD i386 under qemu
Architecture: i386
Machine: i386
>Description:

The NetBSD-current boot floppies no longer boot.  I found this with
the boot-com1.fs floppy on a qemu i386 host, but I assume it also
affects other floppies and architectures as well as physical hosts.

Using an automated binary CVS search, I have determined that this
regression appeared with src/distrib/common/buildfloppies.sh revision
1.14.  Revision 1.15 remains broken.

I suspect the problem may be caused by the fact that the first file in
the tar archive contained on the floppy is now "." rather than "boot".

>How-To-Repeat:

Run the following commands:

  ftp 
ftp://ftp.netbsd.org/pub/NetBSD-daily/HEAD/200811090002Z/i386/installation/floppy/boot-com1.fs
  qemu -nographic -serial stdio -fda boot-com1.fs

and observe that qemu hangs immediately.

>Fix:

Revert buildfloppies.sh to 1.13.
