Add nbdkit-floppy-plugin, “inspired” by qemu's VVFAT driver, but without the ability to handle writes. The implementation is pretty complete, supporting FAT32, LFNs, volume labels, timestamps, etc, and it passes both ‘make check’ and ‘make check-valgrind’. Usage is simple; to serve the current directory: $ nbdkit floppy . Then using guestfish (or any NBD client): $ guestfish --ro

Create a virtual FAT-formatted floppy disk from a directory of files. For example: nbdkit floppy /path/to/directory The implementation of this is quite different from nbdkit-iso-plugin since we cannot use an external program. Instead this plugin synthesizes the MBR partition and FAT32 structures that are required. To do: Implement bootable virtual floppy using syslinux. This is not
