| This file will contain a list of notable changes for each release. Note | ||||
| the information in this file is in reverse order. | ||||
|  | ||||
| ## OpenRC 0.33 | ||||
|  | ||||
| This version removes the "service" binary which was just a copy of | ||||
| "rc-service" provided for compatibility. | ||||
|  | ||||
| If you still need the "service" binary, as opposed to "rc-service", it is | ||||
| recommended that you use something like Debian's init-system-helpers. | ||||
| Otherwise, just use "rc-service" in place of "service". | ||||
|  | ||||
| ## OpenRC 0.31 | ||||
|  | ||||
| This version adds support for Control Groups version 2, which is | ||||
| considered stable as of Linux-4.13. Please see /etc/rc.conf for | ||||
| documentation on how to configure control groups. | ||||
|  | ||||
| ## OpenRC-0.28 | ||||
|  | ||||
| This version mounts efivars read only due to concerns about changes in | ||||
| this file system making systems unbootable.  If you need to change something | ||||
| in this path, you will need to re-mount it read-write, make the change | ||||
| and re-mount it read-only. | ||||
|  | ||||
| Also, you can override this behavior by adding a line for efivars to | ||||
| fstab if you want efivars mounted read-write. | ||||
|  | ||||
| For more information on this issue, see the following url: | ||||
|  | ||||
| https://github.com/openrc/openrc/issues/134 | ||||
|  | ||||
| ## OpenRC-0.25 | ||||
|  | ||||
| This version contains an OpenRC-specific implementation of init for | ||||
| Linux which can be used in place of sysvinit or any other init process. | ||||
| For information on its usage, see the man pages for openrc-init (8) and | ||||
| openrc-shutdown (8). | ||||
|  | ||||
| ## OpenRC-0.24.1 | ||||
|  | ||||
| This version starts cleaning up the dependencies so that rc_parallel | ||||
| will work correctly. | ||||
|  | ||||
| The first step in this process is to remove the 'before *' from the | ||||
| depend functions in the clock services. This means some  services not | ||||
| controlled by OpenRC may now start before instead of after the clock | ||||
| service. If it is important for these services to start after the clock | ||||
| service, they need to have 'after clock' added to their depend | ||||
| functions. | ||||

| Under Linux, OpenRC can use cgroups for process management as well. Once | ||||
| the kernel is configured appropriately, the `rc_cgroup_mode` setting in | ||||
| /etc/rc.conf should be used to control whether cgroups version one,, | ||||
| two, or both are used. The default is to use both if they are available. | ||||
|  | ||||
| By changing certain settings in the service's `conf.d` file limits can be | ||||
| enforced per service. These settings are documented in detail in the | ||||
| default /etc/rc.conf under `LINUX CGROUPS RESOURCE MANAGEMENT`. | ||||
|  | ||||
| # Dealing with Orphaned Processes | ||||
|  | ||||
| It is possible to get into a state where there are orphaned processes | ||||
| running which were part of a service. For example, if you are monitoring | ||||
| a service with supervise-daemon and supervise-daemon dies for an unknown | ||||
| reason. The way to deal with this will be different for each system. | ||||
|  | ||||
| On Linux systems with cgroups enabled, the cgroup_cleanup command is | ||||
| added to all services. You can run it manually, when the service is | ||||
| stopped, by using: | ||||
|  | ||||
| ``` | ||||
| # rc-service someservice cgroup_cleanup | ||||
| ``` | ||||
|  | ||||
| The `rc_cgroup_cleanup` setting can be changed to yes to make this | ||||
| happen automatically when the service is stopped. | ||||
|  | ||||
| By changing certain values in the `conf.d` file limits can be enforced per  | ||||
| service. It is easy to find orphan processes of a service that persist after  | ||||
| `stop()`, but by default these will NOT be terminated. | ||||
| To change this add `rc_cgroup_cleanup="yes"` in the `conf.d` files for services  | ||||
| where you desire this functionality. | ||||

| .Nm | ||||
| .Sh DESCRIPTION | ||||
| .Nm | ||||
| is an init process which can be an alternative to sysvinit or any other | ||||
| init process. | ||||
| .Pp | ||||
| To use | ||||
| .Nm | ||||
| configure your boot loader to invoke it or symlink it to /sbin/init. | ||||
| Also, you will need to use | ||||
| .Xr openrc-shutdown 8 , | ||||
| to halt, reboot or poweroff the system. | ||||
| .Pp | ||||
| The default runlevel is read from the init command line, the | ||||
| rc_default_runlevel setting in rc.conf, the kernel command line, or it is | ||||
| assumed to be "default" if it is not set in any of these places. | ||||
| .Pp | ||||
| .Nm | ||||
| doesn't manage getty's directly, so you will need to manage them another | ||||
| way. For example, you can use the agetty service script as described in | ||||
| agetty-guide.md in this distribution. | ||||
| .Sh BUGS | ||||
| This was first released as part of OpenRC 0.25. | ||||
| I do not know of any specific issues. However, since this is the first | ||||
| release of openrc-init, please test and report any issues you find. | ||||
