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.

||||

|

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.
