Files in /etc are conf files, and are not overwriten on upgrades.
Either (it will ask you) it will install the new one and rename the old
one to .dpkg_old, or it will leave the old one and install the new one
as .dpkg_new (that is the default).  It even lets you view a diff to
decide if the changes make sense or not before deciding.  You then go
fix it manually if any of the new things are things you need, or to add
your own changes to the new file.

And of course Debian doesn't have a /etc/rc.d dir either, as that isn't
part of the FHS standard.
