This role can configure sysctl values (/proc/sys) and sysfs values (/sys).
The role configures sysctl values (under /etc/sysctl.d/) and restarts systemd-sysctl afterwards to apply them.
The file the sysctl values is written to is called XX-ansible.conf where XX is a configurable number (default: 10).
This allows to set the priority of the file if other packages/modules also place sysctl configurations to /etc/sysctl.d/.
Note that when changing the value, the old file is not automatically removed.
The role installes the sysfsutils package and uses its /etc/sysfs.d/ directory to configure persistent sysfs values.
Then it applies these values by restarting the sysfsutils service.
The file the sysctl values is written to is called XX-ansible.conf where XX is a configurable number (default: 10).
This allows to set the priority of the file if other packages/modules also place sysctl configurations to /etc/sysfs.d/.
Note that when changing the value, the old file is not automatically removed.
