## 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:

# ulimit and CGroups
Setting `ulimit` and `nice` values per service can be done through the
`rc_ulimit` variable.
Setting `ulimit` and `nice` values per service can be done through the `rc_ulimit`
variable.
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.
Under Linux, OpenRC can optionally use CGroups for process management.
By default each service script's processes are migrated to their own CGroup.
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.
