934530914b add "unsupervised" status and return code 64 to supervise-daemon status function
This is to be used if the service is being supervised and the
supervisor is somehow killed.

Currently, this is very linux specific, but I will expand to other
platforms, patches are welcome.

3c05db74f6 remove service binary
The service binary was just a synonym for rc-service, so use rc-service
instead of service. If you want a "service" binary, it should be
something that can determine which service manager you are running and
run the appropriate service manager commands.

2b0345165e Make cgroup_cleanup send only one sigterm and sigkill
Instead of looping and sending multiple signals to child processes in
cgroup_cleanup, we send sigterm followed by sleeping one second then
sigkill.

This brings us more in line with systemd's "control group" killmode
setting.

Also, this commit includes several shellcheck cleanups.

the supervisor is started since stopping the supervisor just sends a

This file will contain a list of notable changes for each release. Note

## 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.

# 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 optionally use CGroups for process management.
By default each service script's processes are migrated to their own CGroup.
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.
