=head1 NAME
dh_installinit - install init scripts 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<-d>] [S<B<--> I<params>>]
=head1 DESCRIPTION
dh_installinit is a debhelper program that is responsible for installing
init scripts and associated defaults files into package build directories.
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
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.
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.
=head1 OPTIONS
=over 4
=item B<-n>, B<--noscripts>
Do not modify postinst/postrm/prerm scripts.
=item B<-o>, B<--onlyscripts>
Only modify postinst/postrm/prerm scripts, do not actually install any init
script or default files. May be useful if the init script is shipped and/or
installed by upstream in a way that doesn't make it easy to let
dh_installinit find it.
=item B<-r>, B<--no-restart-on-upgrade>
Do not restart 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 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
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
passed to L<update-rc.d(8)>.
=item B<--name=>I<name>
Install 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, dh_installinit looks for and installs files named
debian/package.name.init and debian/package.name.default, instead of the
usual debian/package.init and debian/package.default.
=item B<--init-script=>I<scriptname>
Use "scriptname" as 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). 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 parameter is deprecated, use the --name parameter instead.
=item B<--error-handler=>I<function>
Call the named shell function if running the init script fails. The
function should be provided in the prerm and postinst scripts, before the
#DEBHELPER# token.
=back
=head1 NOTES
Note that this command is not idempotent. "dh_clean -k" should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
