Ok.  Thanx for the info!

What I do on debian, and debian-ish systems, is to RCS version all
config files I touch.  When an upgrade brings in a new version of the
file, I check that in, and put in my custom settings (for cyrus, it's
using imaps, and allowing 8 bit headers to survive).

So when the packager introduces new settings I usually adopt them (it's
on the principle that when the upstream package changes, it's less
hassle to change with it, than to stay with settings and behaviour that
may become unsupported at some point in time).

I have to think about this, and try to understand what happened.

Thanx again!
