Tuned is really nice because it supports many different kernel, cpu, disk, power, bootloader (very limited), etc. settings in one shot, and provides sysfs setting persistence on rhel/fedora.

So I thought I might have a go at creating a kernel\_settings module implemented by importing the tuned code as a “library”. However, it’s getting pretty complex pretty quickly - WIP: [https://github.com/richm/kernel\_settings/blob/master/library/kernel\_settings.py](https://github.com/richm/kernel_settings/blob/master/library/kernel_settings.py)

- Have to defeat tuned logging - [https://github.com/richm/kernel\_settings/blob/master/library/kernel\_settings.py#L19-L54](https://github.com/richm/kernel_settings/blob/master/library/kernel_settings.py#L19-L54)

- Hard to tell the difference between when tuned reports that a profile file was not found vs. had some other problem reading the tuned profile: [https://github.com/richm/kernel\_settings/blob/master/library/kernel\_settings.py#L129-L150](https://github.com/richm/kernel_settings/blob/master/library/kernel_settings.py#L129-L150)

- Have to convert the ansible dict parameters to a tempfile in order to create a tuned profile data type: [https://github.com/richm/kernel\_settings/blob/master/library/kernel\_settings.py#L152-L178](https://github.com/richm/kernel_settings/blob/master/library/kernel_settings.py#L152-L178)

- Have to use some protected members of internal tuned data structures: [https://github.com/richm/kernel\_settings/blob/master/library/kernel\_settings.py#L222](https://github.com/richm/kernel_settings/blob/master/library/kernel_settings.py#L222) and [https://github.com/richm/kernel\_settings/blob/master/library/kernel\_settings.py#L145](https://github.com/richm/kernel_settings/blob/master/library/kernel_settings.py#L145)

I’m looking for some guidance from ansible module developers if this seems worth pursuing or maybe I should just use the sysctl module + implement my own sysfs support + use other existing modules.
