| ## 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. | ||||

| Under Linux, OpenRC can optionally use CGroups for process management. | ||||

| 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. | ||||
