I figure sooneror later we'll have more of these docs, hence let's give
them a clean place to be.
This leaves NEWS and README/README.md as well as the LICENSE texts in
the root directory of the project since that appears to be customary for
Free Software projects.
The DNS and NTP fallback server situation is pretty similar, and
downstream distros might want to change both to whatever they need,
hence mention them both.
It is impossible to ship a fully generic PAM configuration upstream.
Therefore, ship a minimal configuration with the systemd --user requirements,
and add a note to DISTRO_PORTING documenting this.
Fixes#4284
f33d3ec1 (move more common files to shared/ and add them to shared.la,
2012-04-12) moved src/hostname-setup.c to src/shared/hostname-setup.c,
but did not update DISTRO_PORTING accordingly. Fix this.
