=head1 NAME

dh_installinit - install init scripts and/or upstart jobs into package build directories

=cut

use strict;
use Debian::Debhelper::Dh_Lib;

=head1 SYNOPSIS

B<dh_installinit> [S<I<debhelper options>>] [B<--name=>I<name>] [B<-n>] [B<-R>] [B<-r>] [B<-d>] [S<B<--> I<params>>]

=head1 DESCRIPTION

B<dh_installinit> is a debhelper program that is responsible for installing
init scripts with associated defaults files, as well as upstart job files
into package build directories.

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/> to start and stop
the init scripts.

=head1 FILES

=over 4

=item debian/I<package>.init

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

=item debian/I<package>.default

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

=item debian/I<package>.upstart

If this exists, it is installed into etc/init/I<package>.conf in the package
build directory.

=head1 OPTIONS

=over 4

=item B<-n>, B<--noscripts>

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.

=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 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 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/> , and 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 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 init script (and default file) as well as upstart job 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.init>,
F<debian/package.name.default> and F<debian/package.name.upstart>
instead of the usual F<debian/package.init>, F<debian/package.default> and
F<debian/package.upstart>.

=item B<--init-script=>I<scriptname>

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 is incompatible with the use of 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.

=back

=head1 NOTES

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.
