This is all very exciting.  I just took a ssh tour through all my remote 
systems and everything looks great.  Even my one disrespectful system is 
now toeing the ntp line.  I believe the addition of noselect resolved 
that one.  Is there a reason to even include 28.0 if we tag it with 
noselect?

With that soft link suggested by David I think this is moot now, but in 
any case...

address@hidden:~$ pstree -paul | fgrep ntpd
  |-ntpd,518,ntp -p /var/run/ntpd.pid -g -u 107:114
  |               |-grep,1910 -F ntpd

Not good as in it is strongly suggested to update, or not good as in the 
newer versions solve a lot of bugs but since it's working for you just 
go with it?
