dh_runit - install/enable runit runscripts


dh_runit [debhelper options] [path options] ...


dh_runit is a debhelper program that is responsible for installing and enabling runit runscripts. If a file named debian/package.runit exists, then it ensures appropriate actions are performed based on its content.

For runit, each unit of supervision (or, simply speaking, program) is represented by a directory under /etc/sv, containing at least a run executable file. Each enabled unit of supervision is represented by a symbolic link under /etc/services (which itself is a symbolic link to /etc/runit/runsvdir/default) pointing to some directory under /etc/sv.

dh_runit reads arguments from the command line and debian/package.runit in pairs, with the first item being the path to a file or directory and the second being a set of options. If the first argument names a file, it is treated as a 'run' script to be installed at /etc/sv/*/run as an executable file. If the first argument names a directory, that directory is copied as a whole to /etc/sv.

Options are comma separated, like mount options. Unrecognized options are errors. The following options are recognized:

Install the runscript but do not enable it by default. This means that the corresponding service will not be started. The service can be enabled manually by the system administrator or automatically using update-service(8).
By default, the name of the directory under /etc/sv for a given runscript is the basename of the path argument naming it. This option allows overriding that default with an explicitly chosen directory name.
Install a standard log/run script that invokes svlogd(8) with the rights of the dedicated user. Specifying this option produces an error if the path argument names a directory that already contains a /log/run script.
This option controls what to do during the upgrade of a service when runit is PID 1; it takes one of the following strings as argument:

restart restart the service in postinstall, after all files of the package are unpacked and the upgrade is complete. This is the same as dh_installinit or dh_installsystemd ' --restart-after-upgrade '. This is the implicit default if the 'onupgrade' option is not set.

stop stop the service in prerm and start again in postinst. This option is useful if the daemon get confused by the package being upgraded while it's still running. This is the same as dh_installinit or dh_installsystemd '--no-restart-after-upgrade'.

nostop do not stop service on upgrade. This has the side-effect of not restarting the service as a part of the upgrade. Use this option when the service does not support being restarted while it's running. Display managers (xdm, slim, ...) are example of non-restartible services. When this option is set the invoke-run interpreter, provided by runit package, will refrain from automatically replace the sysvinit-managed instance of the service with a runit-managed instance (replacement requires manual intervention or a system restart). This is the same as dh_installinit or dh_installsystemd '--no-stop-on-upgrade'.

reload similar to nostop, but the service configuration is reloaded (HUP) during the upgrade. This might be useful in cases (like dbus) where the service does not support restarting on upgrade and where reloading the config instead of restarting makes sense. When this option is set the invoke-run interpreter, provided by runit package, will refrain to automatically replace the sysvinit-managed instance of the service with a runit-managed instance (replacement requires manual intervention or a system restart).

Please note that onupgrade does not control whether the service will be started after the first install of the package; by default the service is always started if it's enabled (and stopped before removal). To not start the service after the first install you should use the 'disable' option.

Since dh-runit 2.8.15 this option is no longer needed and is deprecated. It's retained only for backward compatibility with packages that still use it. See #942323
Since dh-runit 2.9.0 this option is deprecated and it's retained only for backward compatibility. You can use onupgrade=nostop instead.
With this option dh-runit will not add its snippets to maintscripts; actions like enable or disable, start, stop and restart the service need manual editing of maintaner scripts.
With this option dh-runit will install the service directory under /usr/share/runit/sv/ instead of the default /etc/sv/. Maintainers should not use this option to ship a runit service together with a daemon, this option is only intended for a catch-all runscript package. If this option is not used together with 'noscript' dh-runit exists with an error as the snippets from dh-runit expects the service to be shipped under /etc/sv/ and a mechanism to automatically copy the service into /etc/sv/ is not provided.
Do not install a standard finish file with the service; maintaners that want to provide a custom finish file do not need to use this option as if a finish file already exists in the service directory it will prevail over the default. This option is only needed when for some reason it's not convenient to have a finish file at all.
Include presubj file for reportbug into generate package. This file contains note that suggest including runit maintainers into copy of bug reports, related to runit integration. If the package already include it's own presubj file, that file takes precedence over runit presubj file.

This may make life of package maintainer who uses another init system easier.

If you don't need other options, specify this one.


Packages using dh_runit do not depend on runit but should include the runit:Breaks variable in their Breaks field in debian/control to ensure that no breakages are caused by a too-old version of runit package.


This section contains several example package.runit snippets.

  # In this case, a file is installed as a 'run' script. The directory
  # name under /etc/sv is derived from the file's basename (/etc/sv/script).
  path/to/file/to/be/installed/as/run/script defaults

  # Similar, but installs a directory as a whole. It is the package's
  # responsibility to ensure this directory contains everything required.
  path/to/directory defaults

  # Similar, but without creating a symlink under /etc/service.
  path/to/directory disable

  # Explicitly specifying a name to use for the directory under /etc/sv.
  # A standard log/run script will be created.
  path/to/directory name=my-preferred-name,logscript
