Fedora Update Notification
FEDORA-2019-1b30db2125

Name : nbdkit
Product : Fedora 30
Version : 1.12.8
Release : 1.fc30
URL : https://github.com/libguestfs/nbdkit
Summary : NBD server
Description :
NBD is a protocol for accessing block devices (hard disks and
disk-like things) over the network.

nbdkit is a toolkit for creating NBD servers.

The key features are:

* Multithreaded NBD server written in C with good performance.

* Minimal dependencies for the basic server.

* Liberal license (BSD) allows nbdkit to be linked to proprietary
libraries or included in proprietary code.

* Well-documented, simple plugin API with a stable ABI guarantee.
Lets you to export "unconventional" block devices easily.

* You can write plugins in C or many other languages.

* Filters can be stacked in front of plugins to transform the output.

In Fedora, 'nbdkit' is a meta-package which pulls in the core server
and a useful subset of plugins and filters.

If you want just the server, install 'nbdkit-server'.

To develop plugins, install the 'nbdkit-devel' package and start by
reading the nbdkit(1) and nbdkit-plugin(3) manual pages.
