[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

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.

[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
