dh_installtmpfiles - install tmpfiles.d configuration files
dh_installtmpfiles [debhelper options][--name=name]
dh_installtmpfiles is a debhelper program that is responsible for installing package maintainer supplied tmpfiles.d configuration files (e.g. for systemd-tmpfiles).
It also finds the tmpfiles.d configuration files installed by a package and generates postinst code blocks for activting the tmpfiles.d configuration when the package is installed. These snippets are added to the maintainer scripts by dh_installdeb(1).
This command is not idempotent. dh_prep(1) should be called between invocations of this command (with the same arguments). Otherwise, it may cause multiple instances of the same text to be added to maintainer scripts.
