Not only at install time. At runtime too. If you look at
/etc/exim4/update-exim4.conf.conf, you'll see an that there is a
dc_use_split_config='true'
This option specifies whether you want update-exim4.conf to build the
running config from the conf.d config (many files) or to copy it from a
monolithic /etc/exim4/exim4.conf file.
