Use usr/local/bin instead of usr/bin for Silverblue and other immutable OSs

[gimbling-away]

Fixes #394

[AdnanHodzic]

Great stuff and thank you for your contribution!

[gimbling-away]

For future references: This should make it also compatible with OpenSUSE MicroOS and other immutable operating systems.

[SunkenHero]

Great work.

@gimbles while reviewing #459 I noticed a particular regression introduced with this PR.

Namely, prior to these changes if you perform an install auto-cpufreq with sudo ./auto-cpufreq-installer --install followed by installation of daemon sudo auto-cpufreq --install, then you decide to remove everything with sudo ./auto-cpufreq-installer --remove you'll get following output:

sudo ./auto-cpufreq-installer --remove 

--------------------- Removing auto-cpufreq daemon ----------------------

* Turn on bluetooth on boot

----------------------------------- Warning -----------------------------------

Detected GNOME Power Profiles daemon service is stopped!
This service will now be enabled and started again.

* Enabling GNOME power profiles
Removed "/etc/systemd/system/power-profiles-daemon.service".
Created symlink /etc/systemd/system/graphical.target.wants/power-profiles-daemon.service → /lib/systemd/system/power-profiles-daemon.service.

------------------ Running auto-cpufreq daemon removal script ------------------

* Stopping auto-cpufreq daemon (systemd) service

* Disabling auto-cpufreq daemon (systemd) at boot
Removed "/etc/systemd/system/multi-user.target.wants/auto-cpufreq.service".

* Removing auto-cpufreq daemon (systemd) unit file

* Reloading systemd manager configuration
reset failed

------------------------- auto-cpufreq daemon removed -------------------------

auto-cpufreq successfully removed.

-------------------------------------------------------------------------------


-------------------------------------------------------------------------------

auto-cpufreq tool and all its supporting files successfully removed.

-------------------------------------------------------------------------------

However, after these changes have been merged if you do the same steps as mentioned above, you'll only be presented with:

sudo ./auto-cpufreq-installer --remove 

-------------------------------------------------------------------------------

auto-cpufreq tool and all its supporting files successfully removed.

-------------------------------------------------------------------------------

I'd really like if same more verbose removal output was brought back as it gives more clarity to user on what happened. Can you please create a new PR for this? Thank you

I don't really have an idea on why this regression is caused.

I didn't even touch the installer, just replaced a few paths in core.py

@gimbles I know, I'm also baffled myself. But have tracked it down where d77c1de commit (one before these changes were merged) doesn't have this behavior.

@SunkenHero can you confirm if you have this problem as well?

The installer script just evaluates and runs /usr/local/bin/auto-cpufreq --remove when it tests that auto-cpufreq-remove exists.

If this test fails, then it's likely that nothing is removed and the function silently goes on to print auto-cpufreq tool and all its supporting files successfully removed.

This would also explain the lack of messages.

We should add a check in the installer to see if the test is successful or not, which would also help in debugging this particular issue. So something like this:

  if [ -f $srv_remove ]; then
    eval $tool_proc_rm
  else
  	separator
	printf "Failed to uninstall"
	separator
	return 1;
  fi

@abvee please give it a try and needless to say create a PR if you're successful :)

I have some code, but I'm a bit lost on what to do with it. It's my first time actually contributing to a repository, so I'm not sure what best practice here is..... do I make a fork of @gimbles repository or just a new branch and PR on my own fork that includes my installer changes ?

[AdnanHodzic]

@abvee you would create a PR from auto-cpufreq master branch. Changes made in this PR by @gimbles have already been merged.

But what about the changes I have made to the installer in #459 that have not been merged yet ? Do I modify the original install script and let you do the merging ? Sorry for all the unrelated questions, couldn't find any proper answers on google :(

Don't worry about it, I'll merge it as soon as this regression has been fixed. Reason why I didn't merge it yet is I'm trying to reduce entropy around this issue.
