[PATCH nbdkit 0/3] Add partitioning plugin.
nbdkit partitioning boot.img swap.img root.img
... creates a virtual disk by adding a partition table.
In ancient times Xen used to do this.

[PATCH nbdkit v3 0/4] Add linuxdisk plugin.
For v3 I reimplemented this using mke2fs -d. This obviously makes the
implementation a whole lot simpler, but cannot support multiple
directory merging.
Patches 1-3 are the same as before. I've also reproduced the notes
from v2 below.
v2:
- Fix inconsistent tab/space.
- All 3 plugins now contain a block of text pointing to the
other 2 plugins.
- TMDIR -> TMPDIR
- Unlink the

[PATCH nbdkit v3 0/3] Add partitioning plugin.
The partitioning plugin patch is the same (except for rebasing).
However I have changed the first two patches based on feedback
received. In particular this fixes a very serious bug found by Eric
Blake in the current truncate filter.

[PATCH nbdkit v2 0/5] Add linuxdisk plugin.
Another interesting thing you can do with this plugin:
https://rwmj.wordpress.com/2019/02/19/nbdkit-linuxdisk-plugin/
v2:
- Fix inconsistent tab/space.
- All 3 plugins now contain a block of text pointing to the
other 2 plugins.
- TMDIR -> TMPDIR
- Unlink the temporary file and other cleanups along error paths.
- fclose -> pclose, and check the return value for errors.

[PATCH nbdkit 0/4] New plugin: Add linuxdisk plugin.
Turns out Japanese trains are good for coding!
In supermin we have a bunch of code to create the libguestfs
appliance. It creates it directly using libext2fs (part of
e2fsprogs). We can use the same technique to create ext2 virtual
disks in nbdkit, which is what this new plugin does. Why a new plugin
instead of modifying the floppy plugin? See the 4/4 commit message
for an explanation.
