 dh_installmodules is a debhelper program that is responsible for
 registering kernel modules.
 
-Files named debian/package.modules will be installed as
-etc/modutils/package in the package build directory. This is for use by
-modutils. Files named debian/package.modprobe will be installed in

+Files named debian/package.modprobe will be installed in
+etc/modprobe.d/package.conf in the package build directory, to be used by
 module-init-tools's version of modprobe.
 
-Then postinst and postrm commands are automatically generated to register
-the modules when the package is installed. See L<dh_installdeb(1)> for an
-explanation of how this works. Note that this will be done for any
-package this program acts on which has either a package.modules or
-has .o or .ko files in /lib/modules.
+Kernel modules are searched for in the package build directory and if
+found, postinst and postrm commands are automatically generated to 
+run depmod and register the modules when the package is installed. 
+These commands are inserted into the maintainer scripts by dh_installdeb.
+See L<dh_installdeb(1)> for an explanation of how this works.
+
+Previous versions of dh_installmodules installed files named
+etc/modprobe.d/package, code is added to the preinst and postinst to
+handle the upgrade from the old location.
+
+Previous versions of dh_installmodules also supported 
+files named debian/package.modules, which were installed into 
+etc/modutils/package in the package build directory. This was for use by
+modutils, which is no longer in Debian. dh_installmodules will warn about
+such files now.
