Subject: [PATCH] Systemd service unit files.
As of August 2014, all Linux distributions include systemd and most of
them enable it by default.
https://en.wikipedia.org/wiki/Systemd#Adoption
There are many systemd HOWTOs, like:
https://wiki.archlinux.org/index.php/systemd
https://coreos.com/docs/launching-containers/launching/getting-started-with-systemd/
https://fedoraproject.org/wiki/Packaging:Systemd
For description of options in the service files, see:
http://www.freedesktop.org/software/systemd/man/systemd.unit.html
http://www.freedesktop.org/software/systemd/man/systemd.service.html
Installation of these files is turned on with --enable-systemd
configure option. They are installed into
PREFIX/lib/systemd/system/ by default. One can also
use --with-systemd-unitdir to specify another directory.
For now the template files reside in src/bin/keactrl/
as I haven't figured out a better place.
