87cfad3d6c cgroup2_set_limits: verify that the cgroup2 path is a mount point
prior to cgroups getting mounted, /sys/fs/cgroup will still exist,
but attempts to make directories in it will fail, change cgroup2_set_limits() to
verify that cgroups are mounted instead of just checking that /sys/fs/cgroup
exists.

This fixes #307.
This fixes #321.

894995176e Revert "remove /run migration script"
For some reason removing this broke the build.

This reverts commit 5246ea7b6f.

5246ea7b6f remove /run migration script
We have used /run for some time now and we have had this migration
script for 6 years. Linux users should have upgraded by now to a version
of OpenRC which stores its information in /run.

5427783fdf standardize the default shell
I do not know of a need to have the default shell be a build-time
configurable setting. All *nix systems I am aware of have /bin/sh as a
default posix compatible shell.
If some systems running OpenRC do not make that assumption about
/bin/sh, I will consider bringing this back, so feel free to open an
issue.

d95425b08a rc-cgroup.sh: remove shebang line
This is not a stand-alone script, so it does not need the shebang line.
This also means it is not necessary to run this through sed.

af70862a7a supervise-daemon: use a default pid file if one is not specified
Since the pid file is internal to us, start moving toward deprecating it
by not requiring the user to specify it.
In the next release, I plan on working on code to start phasing out the
use of a pid file if this is possible.

0f704402a2 supervise-daemon: make the pidfile an implementation detail
The pidfile of the supervisor doesn't need to be adjustable by the
service script. It is only used so the supervisor can stop itself when
the --stop option is used.

c1e582586d supervise-daemon: add health checks
Health checks are a way to monitor a service and make sure it stays
healthy.

If a service is not healthy, it will be automatically restarted after
running the unhealthy() function to clean up.

16ff3cd8df check whether /sys/fs/cgroup is a mountpoint
The current check only tries to detect whether /sys/fs/cgroup exists and
whether it is writable or not. But when the init system doesn't mount
cgroups then /sys/fs/cgroup will just be an empty directory. When paired
with unprivileged containers that mount sysfs this will cause misleading
errors to be printed since /sys/fs/cgroup will be owned by user
nobody:nogroup in this case. Independent of this specific problem this
check will also be misleading when the /sys/fs/cgroup exists and is in
fact writable by the init system but isn't actually a mountpoint.

Note from William. "grep -qs" doesn't need to redirect output to
/dev/null since it is completely silent.

This fixes #209.

ddbdb69658 add more variables for start-stop-daemon and supervise-daemon options
Add the following variables to expose more arguments that can be passed
to start-stop-daemon or supervise-daemon:

- directory will be passed to --chdir
- error_log will be passed to --stderr
- output_log will be passed to --stdout
- umask will be passed to umask

This is for #184.

a428c325a9 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.

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.

17b5cc78d3 add retry option to supervise-daemon
The --retry option for supervise-daemon defines how the supervisor will
attempt to stop the child process it is monitoring. It is defined when
the supervisor is started since stopping the supervisor just sends a
signal to the active supervisor.

This fixes #160.
