Right, that's what I was thinking about. collectdctl uses the UNIXSOCK
interface to communicate with collectd. So after implementing my
proposed change for that, collectdctl could be updated to support the
new command as well.

Ack. I'm not sure, though, if it's a good idea to implement that before
most/many/all parts of collectd actually support "reconfigure" as people
might expect too much from SIGHUP else.

Before adding support for SIGHUP, a reload could be done through the
UNIXSOCK mechanism. This would allow the daemon (and the caller) to
directly display any (error) messages to the user. This can also be
implemented in an init script (or similar), so the user will get
(another) very familiar interface (with the side-note that the
'unixsock' plugin will have to be enabled).

Thoughts about that?
