 dh_installudev is a debhelper program that is responsible for
 installing udev rules files.
 

-Files named debian/package.udev will be installed as
-etc/udev/package.rules in the package build directory.
+Code is added to the preinst and postinst to handle the upgrade from the
+old udev rules file location.

 
 

-Then postinst and postrm commands are automatically generated to enable
-the rules file when the package is first installed, by creating a symlink
-to it in the /etc/udev/rules.d/ directory. These commands are inserted into
-the maintainer scripts by dh_installdeb. See L<dh_installdeb(1)> for an
-explanation of how this works.
