That is strange. Is  /tmp/boot.flp an existing image? If so, what size is it?

Note that is you use touch on a non-existing file, it will create a file 0
bytes long! If you try to mount that, you'll get an error, because there is no
data to be read.

Yes.

If you want to _create_ a floppy image, you can use:

    dd if=/dev/zero bs=1k count=1440 of=boot.flp

Then use mdconfig to make an md device out of it. Of course you'll have to
create an msdos filesystem on it;

    newfs_msdos /dev/md0

After that you can mount it and fill it with whatever you like.
