[chrony-dev] refclock prefer and log

[Håkan Johansson <f96hajo@xxxxxxxxxxx>]

Hi,

I'm testing chrony (current git) with two GPS reference clocks, but am 
suffering from chrony moving between the two equally good sources as 
reference clock.

It would be nice with an option akin to the ntpd 'prefer' to force one of 
the two (when it is an eligible source, i.e. OK for sync).

ntpd also has a keyword 'noselect' which prevents a server from being used 
as reference clock.  I've found that quite useful to let a good ntpd 
instance do monitoring of other machines, without the risk of them being 
used as reference.

As far as I could see, refclock measurements in chronyd are not logged to 
any file?  It could be nice with a /var/log/chrony/refclock.log or 
something such, updated on each successful dpoll.

Cheers,
Håkan
