Vicente Olivert Riera

Tue Oct 13 10:18:13 UTC 2015
The content of the saned.socket and saned at .service files is based on the
instructions of the sane-backends manual.
Signed-off-by: Vicente Olivert Riera <Vincent.Riera at imgtec.com>

Changes v2 -> v3:
- Create the "target.wants" directories for the socket and the service
and put symlinks in there pointing to the real files. (Suggested by
Maxime Hadjinlian)
Changes v1 -> v2:
- Install the systemd files in /usr/lib/systemd/system. (Suggested by
Maxime Hadjinlian)
- Create saned user and group (Highlighted by Maxime Hadjinlian)
- Amend the commit log since we are not using the location for the
systemd files specified in the manual.
