[j-nsp] deleting ntp server from config, perhaps a bug?

Yup, this one's on my list of features I haven't added yet.  The
plan was to have the value contain both the DNS and the address so
we (a) always have an address, and (b) can re-resolve at some
specific future time.  It's less of an issue for NTP, but imagine
having DNS fail for your syslog server and not getting logs.  The
re-resolve would be an explicit action, done at the user's direction
(or via event policy, etc).

Anyway, it would look something like:

    [edit system ntp]
    drew at charlie# show
    server 0.pool.ntp.org%216.230.228.242;
    server 1.pool.ntp.org%45.79.109.111;
    server 2.pool.ntp.org%172.98.193.44;
    server 3.pool.ntp.org%69.195.159.158;

where the junos system components would see only the address, but
the UI would hold both and "request system configuration resolve"
would perform the magic.  There'd be an "opt in" knob to turn on
this new behavior, so API clients (and humans) wouldn't freak at
these hybrid values.

Thanks,
