OpenEmbedded layer adding support for OpenRC

Introduction

This layer adds support for OpenRC to OpenEmbedded similarly to how rc.d scripts and systemd are supported. OpenRC can be selected by adding this layer and adding openrc to DISTRO_FEATURES.

Both the standard rc.d scripts and those from OpenRC expect to live in /etc/init.d. When openrc is added to DISTRO_FEATURES, the former will be removed from that directory entirely and only OpenRC capable scripts will be installed [1]. If openrc is not added to DISTRO_FEATURES this layer will not have any effect aside from providing the openrc recipe.

1. This assumes that this layer has an append for the recipe in question.

Dependencies

The meta-openrc layer depends on:

URI: https://git.openembedded.org/openembedded-core
layers: meta
branch: kirkstone

Contributing

Feel free to to use the github pull request UI or to directly send emails to the maintainer(s) using something like:

git send-email -M -1 [email protected] --subject-prefix=meta-openrc][branch][PATCH

Usage

1. Add the layer to your build:

   bitbake-layers add-layer /path/to/meta-openrc

2. Add openrc to DISTRO_FEATURES in your distro or local config:

   DISTRO_FEATURES += "openrc"

3. Update your image to inherit openrc-image and set the following as necessary (see openrc-image.bb for an example):

   1. OPENRC_SERVICES: Define additional services to add to the paired runlevel using a whitespace delimited list of [runlevel]:[service-name].

   2. OPENRC_STACKED_RUNLEVELS: define runlevels to be stacked on top of other runlevels using a whitespace delimited list of [base runlevel]:[stacked runlevel]

Note on pre-kirkstone releases

Prior to kirkstone, this layer used the quick-and-easy approach of relocating openrc scripts to /etc/openrc.d and supplying a single omnibus recipe for additional initd scripts. Images were expected to define their own ROOTFS_POSTPROCESS_COMMAND within which they'd update inittab and add services to runlevels as necessary. With kirkstone, that approach was replaced with a more conventional one following the pattern set by the update-rc.d and systemd bbclasses in openembedded-core.
