@ -731,3 +731,14 @@ usual containers. But unless you have very specific networking needs
that drive you to such a solution, it is probably far preferable to use
`--icc=false` to lock down inter-container communication, as we explored
earlier.
## Editing networking config files
Starting with Docker v.1.2.0, you can now edit `/etc/hosts`, `/etc/hostname`
and `/etc/resolve.conf` in a running container. This is useful if you need
to install bind or other services that might override one of those files.
Note, however, that changes to these files will not be saved by
`docker commit`, nor will they be saved during `docker run`.
That means they won't be saved in the image, nor will they persist when a
container is restarted; they will only "stick" in a running container.
