Be careful when you upgrade in future.

When you upgrade, apt or yum/rpm will notice that you have modified that 
It will create a new one for you (yum/rpm will call it 
You will need to make your change to the new one, then move it into 
place to overwrite the old one.

I frequently have to change that particular template file as it's so 

The apt/yum/rpm command will tell you that it's got a new version of 
that particular file. But it tends to output rather a lot anyway, so 
it's very easy to miss the line that tells you about this file.

'They went with songs to the battle, they were young.
  Straight of limb, true of eye, steady and aglow.
  They were staunch to the end against odds uncounted,
  They fell with their faces to the foe.

  They shall grow not old, as we that are left grow old:
  Age shall not weary them, nor the years condemn.
  At the going down of the sun and in the morning,
  We will remember them.

  They mingle not with their laughing comrades again;
  They sit no more at familiar tables of home;
  They have no lot in our labour of the day-time;
  They sleep beyond England's foam.'
     - Ode of Remembrance, Laurence Binyon
