Running the ntpd service I see lots of messages in /var/log/messages like:
Sep 4 13:02:21 localhost ntpd[302]: frequency file /var/run/ntp.drift.TEMP: Permission denied

Can the user that runs ntpd write to that directory?
Is there a build time configuration that we should tweak?

Can the user that runs ntpd write to that directory?
No. ntpd runs as its own user. /var/run is owned by root.
Is there a build time configuration that we should tweak?
Not that I'm aware of.

Well the obvious way would be to use a directory which is owned by the ntpd user.

I think this fixes the problem. What do you think?
* gnu/services/networking.scm (ntp-shepherd-service): Create new
directory at startup.
