>Organization:
>Environment:
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.

 Does it help to change ". type=dir" to ". type=dir optional"
 in src/distrib/common/buildfloppies.sh ?

 Alas, no.

 Log Message:
 roll back to revision 1.13 until problems mentioned in
 PR 39894
 can be figured out.
 i suspect we can add "boot" to the mtree input, but experimentation
 needs to happen first.

 FS_OPS(ustarfs) can't open files (boot.cfg in that case)
 because files are stored with "./" prefix added by specfile:

 No idea how to specify uid/gid without such prefix.

 I hope that I have fixed this with Makefile.tarfloppy revision 1.15 and 
 buildfloppies.sh revision 1.17.
