[Libguestfs] [PATCH nbdkit 0/4] Add floppy plugin.

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 --format=raw -a nbd://localhost -m /dev/sda1 Welcome to guestfish, the guest filesystem shell for editing virtual machine filesystems and disk images. Type: ‘help’ for help on commands ‘man’ to read the manual ‘quit’ to quit the shell total 2420 drwxr-xr-x 14 root root 16384 Jan 1 1970 . drwxr-xr-x 19 root root 4096 Oct 28 10:07 .. -rwxr-xr-x 1 root root 40 Sep 17 21:23 .dir-locals.el -rwxr-xr-x 1 root root 879 Oct 27 21:10 .gdb_history drwxr-xr-x 8 root root 16384 Oct 28 10:05 .git -rwxr-xr-x 1 root root 1383 Sep 17 21:23 .gitignore -rwxr-xr-x 1 root root 1453 Sep 17 21:23 LICENSE -rwxr-xr-x 1 root root 34182 Oct 28 10:04 Makefile -rwxr-xr-x 1 root root 2568 Oct 27 22:17 Makefile.am -rwxr-xr-x 1 root root 32085 Oct 27 22:18 Makefile.in -rwxr-xr-x 1 root root 620 Sep 17 21:23 OTHER_PLUGINS -rwxr-xr-x 1 root root 4628 Oct 16 22:36 README -rwxr-xr-x 1 root root 4007 Sep 17 21:23 TODO -rwxr-xr-x 1 root root 54733 Oct 27 22:18 aclocal.m4 drwxr-xr-x 2 root root 16384 Oct 27 22:18 autom4te.cache drwxr-xr-x 2 root root 16384 Oct 28 10:04 bash drwxr-xr-x 5 root root 16384 Oct 27 18:07 common [etc] total 560 drwxr-xr-x 4 root root 16384 Oct 28 10:04 . drwxr-xr-x 34 root root 16384 Oct 28 10:04 .. drwxr-xr-x 2 root root 16384 Oct 28 10:04 .deps drwxr-xr-x 2 root root 16384 Oct 28 10:04 .libs -rwxr-xr-x 1 root root 34238 Oct 28 10:04 Makefile -rwxr-xr-x 1 root root 2347 Oct 27 22:17 Makefile.am -rwxr-xr-x 1 root root 33158 Oct 27 22:18 Makefile.in -rwxr-xr-x 1 root root 18181 Oct 28 09:36 directory-lfn.c -rwxr-xr-x 1 root root 5003 Oct 27 22:17 floppy.c -rwxr-xr-x 1 root root 6724 Oct 28 10:04 nbdkit-floppy-plugin.1 -rwxr-xr-x 1 root root 996 Oct 28 10:04 nbdkit-floppy-plugin.la -rwxr-xr-x 1 root root 2547 Oct 27 22:17 nbdkit-floppy-plugin.pod -rwxr-xr-x 1 root root 363 Oct 28 10:04 nbdkit_floppy_plugin_la-directory-lfn.lo -rwxr-xr-x 1 root root 90096 Oct 28 10:04 nbdkit_floppy_plugin_la-directory-lfn.o -rwxr-xr-x 1 root root 342 Oct 28 10:04 nbdkit_floppy_plugin_la-floppy.lo -rwxr-xr-x 1 root root 31720 Oct 28 10:04 nbdkit_floppy_plugin_la-floppy.o -rwxr-xr-x 1 root root 366 Oct 28 10:04 nbdkit_floppy_plugin_la-virtual-floppy.lo -rwxr-xr-x 1 root root 57320 Oct 28 10:04 nbdkit_floppy_plugin_la-virtual-floppy.o -rwxr-xr-x 1 root root 24514 Oct 28 09:56 virtual-floppy.c -rwxr-xr-x 1 root root 9184 Oct 28 09:33 virtual-floppy.h Rich.
