[Pkg-exim4-users] Enhancing update-exim4.conf to accept path to alternate exim4 config directory

[Kay McCormick]

Greetings,

I would like to use update-exim4.conf to test potential configurations 
using a source directory other than /etc/exim4. /etc/exim4 is hard-coded 
into update-exim4.conf with no command-line option to use an alternate 
directory. It should be straight-forward to add an option to accept an 
alternate directory path to use for sourcing the "small files" for 
configuration.

Is this a useful enhancement or is there another best practice for 
developing exim4 configuration changes on debian?
