[Buildroot] [PATCH 1/1] ntp: add systemd unit file for ntpd

[Ivan Sergeev]

Hello Arnout,

1. Yup, I believe so, but it's currently not in place in the skeleton. I
think some of the proposed solutions in the network.service thread would
address this.

2. The symlink into multi-user.target.wants "enables" the service, so that
when systemd needs to reach the multi-user target (which it does when it
boots up), it will run the service. Later, running "systemctl disable" on
the service would remove the symlink, so it isn't run automatically for
that target. So the symlink facilitates enabling/disabling the service for
a given target, but the service file itself should live in
/etc/systemd/system.

Thanks,
~vsergeev
