DH_INSTALLUDEV(1)						     Debhelper							 DH_INSTALLUDEV(1)

NAME
dh_installudev - install udev rules files SYNOPSIS
dh_installudev [debhelperoptions] [-n] [--name=name] [--priority=priority] DESCRIPTION
dh_installudev is a debhelper program that is responsible for installing udev rules files. Code is added to the preinst and postinst to handle the upgrade from the old udev rules file location. FILES
debian/package.udev Installed into lib/udev/rules.d/ in the package build directory. OPTIONS
--name=name When this parameter is used, dh_installudev looks for and installs files named debian/package.name.udev instead of the usual debian/package.udev. --priority=priority Sets the priority string of the rules.d symlink. Default is 40. -n, --noscripts Do not modify preinst/postinst scripts. NOTES
Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command. Otherwise, it may cause multiple instances of the same text to be added to maintainer scripts. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
Joey Hess <joeyh@debian.org> 8.9.0ubuntu2.1 2012-06-12 DH_INSTALLUDEV(1)
