[PATCH 0/3] supermin: add --include-packagelist
Hi,
to ease debugging issues with appliances (e.g. when used in libguestfs),
using --include-packagelist will add a file containing the list of all
the packages used.
Thanks,
Pino Toscano (3):
ext2: add ext2fs_chmod and ext2fs_chown
chroot: factor out file copy code
Add --include-packagelist

[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.
