Description
For future ntp (FreeBSD 10.2+ ntpd 4.2.8p3) usage would it be possible for the web interface to support the pool command (http://doc.ntp.org/4.2.6/manyopt.html#pool)?
Setting multiple servers you run the risk of them not being valid time sources. This is partially mitigated if you're using hosts from the ntp.org's pool project however all to this would go away if you use the pool command.
With ntpd's pool the client's maxclock will be used to set the number of possible peers and bad peers will be rotated out as needed with a since pool line in ntp.conf (https://www.freebsd.org/cgi/man.cgi?query=ntp.conf&sektion=5).

- Target version set to 2.3.1
I've tried this manually and couldn't get any working result from it. Does anyone happen to have a working example of an ntp config with the pool command working as they expect, for comparison?
ntpd accepted the directive but it never did sync up with anything when I tried.

You need to add an extra restrict line for pool:
From my ntp.conf:
...
restrict source limited kod
...
You can find the reasoning here http://lists.ntp.org/pipermail/questions/2010-April/026304.html
