DH_INSTALLINIT(1) Debhelper DH_INSTALLINIT(1)
dh_installinit - install service init files into package build
directories
dh_installinit [debhelper options] [--name=name] [-n] [-R] [-r]
[-d] [-- params]
dh_installinit is a debhelper program that is responsible for
installing init scripts with associated defaults files. In
compatibility levels up to and including 10, dh_installinit will
also install some systemd related files provided by the debian
packaging (see the "FILES" section below). In compatibility
levels up to and including 11, dh_installinit will also handle
upstart jobs provided in the debian packaging (see the "FILES" for
more information on this as well).
It also automatically generates the postinst and postrm and prerm
commands needed to set up the symlinks in /etc/rc*.d/ to start and
stop the init scripts.
In compat 10 or earlier: If a package only ships a systemd service
file and no sysvinit script is provided, you may want to exclude
the call to dh_installinit for that package (e.g. via -N).
Otherwise, you may get warnings from lintian about init.d scripts
not being included in the package.
debian/package.init
If this exists, it is installed into etc/init.d/package in the
package build directory.
debian/package.default
If this exists, it is installed into etc/default/package in
the package build directory.
debian/package.upstart
In compatibility level 11, this file will trigger an error
with a reminder about ensuring the proper removal of the
upstart file in the previous package version. Please consider
using the "rm_conffile" feature from dh_installdeb(1) to
ensure the proper removal of previous upstart files.
In compatibility level 10, if this file exists, it is
installed into etc/init/package.conf in the package build
directory.
debian/package.service
If this exists, it is installed into
usr/lib/systemd/system/package.service in the package build
directory. Only used in compat levels 10 and below.
debian/package.tmpfile
If this exists, it is installed into
usr/lib/tmpfiles.d/package.conf in the package build
directory. Only used in compat levels 10 and below.
-n, --no-scripts
Do not modify postinst/postrm/prerm scripts.
-o, --only-scripts
Only modify postinst/postrm/prerm scripts, do not actually
install any init script, default files, upstart job or systemd
service file. May be useful if the file is shipped and/or
installed by upstream in a way that doesn't make it easy to
let dh_installinit find it.
Caveat: This will bypass all the regular checks and
unconditionally modify the scripts. You will almost certainly
want to use this with -p to limit, which packages are affected
by the call. Example:
override_dh_installinit:
dh_installinit -pfoo --only-scripts
dh_installinit --remaining
-R, --restart-after-upgrade
Do not stop the init script until after the package upgrade
has been completed. This is the default behaviour in compat
10.
In early compat levels, the default was to stop the script in
the prerm, and starts it again in the 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.
--no-restart-after-upgrade
Undo a previous --restart-after-upgrade (or the default of
compat 10). If no other options are given, this will cause
the service to be stopped in the prerm script and started
again in the postinst script.
-r, --no-stop-on-upgrade, --no-restart-on-upgrade
Do not stop init script on upgrade. This has the side-effect
of not restarting the service as a part of the upgrade.
If you want to restart the service with minimal downtime,
please use --restart-after-upgrade (default in compat 10 or
later). If you want the service to be restarted but be
stopped during the upgrade, then please use
--no-restart-after-upgrade (note the "after-upgrade").
Note that the --no-restart-on-upgrade alias is deprecated and
will be removed in compat 12. This is to avoid confusion with
the --no-restart-after-upgrade option. The
--no-stop-on-upgrade variant was introduced in debhelper 10.2
(included in Debian stretch).
--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.
--no-enable
Disable the init script on purge, but do not enable them on
install. This implies a versioned dependency on
init-system-helpers (>= 1.51) as it is the first (functional)
version that supports update-rc.d <script> defaults-disabled.
Note that this option does not affect whether the services are
started. Please remember to also use --no-start if the
service should not be started.
Cannot be combined with -uparams, --update-rcd-params=params,
or -- params.
-d, --remove-d
Remove trailing d from the name of the package, and use the
result for the filename the upstart job file is installed as
in etc/init/ , and 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.)
-uparams --update-rcd-params=params
-- params
Pass params to update-rc.d(8). If not specified, defaults (or
defaults-disabled with --no-enable) will be passed to
update-rc.d(8).
Cannot be combined with --no-enable.
--name=name
Install the init script (and default file) as well as upstart
job file using the filename 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, debian/package.name.default and
debian/package.name.upstart instead of the usual
debian/package.init, debian/package.default and
debian/package.upstart.
--init-script=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. This parameter is incompatible with the use of
upstart jobs.
--error-handler=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.
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.
