[Yann E. MORIN <yann.morin.1998@free.fr>]

Alvaro, All,

On 2014-07-17 11:34 +0200, Alvaro G. M spake thusly:
> dcron doesn't create a pid file, so we run it in foreground but make
> start-stop-daemon create the pidfile and move the daemon to background.
> 
> Give it a number greater than exim's init script, so job output email
> can be sent.

This should be in a DCRON_INSTALL_INIT_SYSV macro, see:
    http://buildroot.org/downloads/manual/manual.html#_infrastructure_for_packages_with_specific_build_systems

Also provide the systemd unit file (if it is available in the package!)
with the DCRON_INSTALL_INIT_SYSTEMD macro.

Regards,
Yann E. MORIN.
