=head1 DESCRIPTION
-dh_installinit is a debhelper program that is responsible for installing
-init scripts and associated defaults files into package build directories.
+B<dh_installinit> is a debhelper program that is responsible for installing
+upstart job files or init scripts with associated defaults files into package
+build directories, and in the former case providing compatibility handling
+for non-upstart systems.
-It also automatically generates the postinst and postrm and prerm commands
-needed to set up the symlinks in /etc/rc*.d/ and to start and stop the init
+It also automatically generates the F<postinst> and F<postrm> and F<prerm> commands
+needed to set up the symlinks in F</etc/rc*.d/> and to start and stop the init
scripts.
-If a file named debian/package.init exists, then it is installed into
-etc/init.d/package in the package build directory, with "package" replaced
-by the package name.
+=head1 FILES
-If a file named debian/package.default exists, then it is installed into
-etc/default/package in the package build directory, with "package" replaced
-by the package name.

+=item debian/I<package>.upstart
+
+If this exists, it is installed into etc/init/I<package>.conf in the package

+
+Otherwise, if this exists, it is installed
+into etc/init.d/I<package> in the package build directory.

+If this exists, it is installed into etc/default/I<package> in the package

=head1 OPTIONS
=item B<-n>, B<--noscripts>
-Do not modify postinst/postrm/prerm scripts.
+Do not modify F<postinst>/F<postrm>/F<prerm> scripts.
+
+=item B<-o>, B<--onlyscripts>
+
+Only modify F<postinst>/F<postrm>/F<prerm> scripts, do not actually install any init
+script, default files, or upstart job. May be useful if the init script or
+upstart job is shipped and/or installed by upstream in a way that doesn't
+make it easy to let B<dh_installinit> find it.
+
+If no upstart job file is installed in the target directory when
+B<dh_installinit --onlyscripts> is called, this program will assume that an
+init script is being installed and not provide the compatibility symlinks
+or upstart dependencies.
+
+=item B<-R>, B<--restart-after-upgrade>
+
+Do not stop the init script until after the package upgrade has been
+completed. This is different than the default behavior, which stops the
+script in the F<prerm>, and starts it again in the F<postinst>.
+
+This can be useful for daemons that should not have a possibly long
+downtime during upgrade. But you should make sure that the daemon will not
+get confused by the package being upgraded while it's running before using
+this option.
=item B<-r>, B<--no-restart-on-upgrade>
-Do not restart daemon on upgrade.
+Do not stop init script on upgrade.
+
+=item B<--no-start>
+
+Do not start the init script on install or upgrade, or stop it on removal.
+Only call B<update-rc.d>. Useful for rcS scripts.
=item B<-d>, B<--remove-d>
-Remove trailing "d" from the name of the package, and use the result for the
-filename the init script is installed as in etc/init.d/ , and the default file
-is installed as in etc/default/ . This may be useful for daemons with names
-ending in "d". (Note: this takes precedence over the --init-script parameter
+Remove trailing B<d> from the name of the package, and use the result for the
+filename the upstart job file is installed as in F<etc/init/> , or for the
+filename the init script is installed as in etc/init.d and the default file
+is installed as in F<etc/default/> . This may be useful for daemons with names
+ending in B<d>. (Note: this takes precedence over the B<--init-script> parameter
described below.)
=item B<-u>I<params> B<--update-rcd-params=>I<params>
=item B<--> I<params>
-Pass "params" to L<update-rc.d(8)>. If not specified, "defaults" will be
+Pass I<params> to L<update-rc.d(8)>. If not specified, B<defaults> will be
passed to L<update-rc.d(8)>.
+=item B<--name=>I<name>
+
+Install the upstart job file or the init script (and default file) using the
+filename I<name> instead of the default filename, which is the package name.
+When this parameter is used, B<dh_installinit> looks for and installs files
+named F<debian/package.name.upstart>, F<debian/package.name.init> and
+F<debian/package.name.default>, instead of the usual F<debian/package.upstart>,
+F<debian/package.init> and F<debian/package.default>.
+
=item B<--init-script=>I<scriptname>
-Use "scriptname" as for the filename the init script is installed as in
-etc/init.d/ (and also use it as the filename for the defaults file, if it
-is installed). This is useful if you need to have an init script with a name
-different from the package's name. Note that if you use this parameter,
-dh_installinit will look to see if a file in the debian/ directory exists
-that looks like "package.scriptname" and if so will install it as the init
-script in preference to the files it normally installs. This feature is really
-only useful if you need a single package to install more than one init script.
+Use I<scriptname> as the filename the init script is installed as in
+F<etc/init.d/> (and also use it as the filename for the defaults file, if it
+is installed). If you use this parameter, B<dh_installinit> will look to see
+if a file in the F<debian/> directory exists that looks like
+F<package.scriptname> and if so will install it as the init script in
+preference to the files it normally installs.
+
+This parameter is deprecated, use the B<--name> parameter instead. This
+parameter will be ignored completely for upstart jobs.
+
+=item B<--error-handler=>I<function>
+
+Call the named shell I<function> if running the init script fails. The
+function should be provided in the F<prerm> and F<postinst> scripts, before the
+B<#DEBHELPER#> token.

+Note that this command is not idempotent. L<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.
