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

These plugins have in common that they store either a list of allocated strings or a list of constant strings. Define either string_vector or const_string_vector as appropriate and use it to store these lists. --- plugins/iso/Makefile.am | 1 + plugins/split/Makefile.am | 1 + plugins/floppy/virtual-floppy.h | 7 +++-- plugins/floppy/directory-lfn.c | 35 +++++++++-------------

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

This was a rather longer trip around the houses than I anticipated! The basic purpose of the patch series is to set $nbdkit_stdio_safe to "0" or "1" in sh and eval plugin scripts. To do that, I ended up adding a nicer way to manipulate environ lists, and to do that, I ended up adding a whole generic vector implementation which is applicable in a lot of different places.
