Replace suggestion of using systemctl edit
Editing `ExecStart=` with `systemctl edit` did
not work for me. Running
`systemctl restart thermald.service` afterwards
was giving errors every time with reason "Unit
thermald.service has a bad unit file setting".

By running `systemctl status thermald.service`,
I was reading this error:

    redis.service has more than one ExecStart=
    setting, which is only allowed for
    Type=oneshot services. Refusing.

By looking through the Internet for answers,
I found a suggestion from a user saying that
"The `ExecStart=` line cannot be modified with
`systemctl edit`"
(https://unix.stackexchange.com/questions/409354).

What worked was replacing the thermald.service file
directly to `/etc/systemd/system/` and
`/usr/lib/systemd/system` worked, as suggested
in the README.md present in the folder containing
example configurations for Surface Pro 5 from
this repository.

# Example Thermald Configuration
This is a minimal thermald configuration, which sets the maximum sustained CPU temperature to about 65°C.
Modify the `<Temperature>65000</Temperature>` value to adapt that to your liking.
Tested on a Surface Book 2, other devices may need adapting, see e.g. the [thermald man page](http://manpages.ubuntu.com/manpages/trusty/man5/thermal-conf.xml.5.html).
More complex and device specific examples can be found in subdirectories
If any subdirectory does not have both files or any dedicated instructions, use the missing files provided here and/or follow these instructions.
## Installation
Both XML files (`thermal-conf.xml` and `thermal-cpu-cdev-order-xml`) need to be placed in the `/etc/thermald/` directory.
Newer thermald versions attempt to automatically load the configuration from ACPI.
If you want to use a manual configuration with such a version, you may need to remove the `--adaptive` option from the systemd service `ExecStart` line.
You can do so by overwriting `thermald.service`. This file is present in `/lib/systemd/system/` (it may also be in `/usr/lib/systemd/system/`).
