1.24.2 is out 😃

There’ll be 1.24.2 released in the next day, so there’s no need to wait for 1.25 😃

The enhancement is in… and it will be available in the next release (1.25) or you can build it yourself if you don’t want to wait 😃

@Ladicle turns out it’s related to how Docker for Mac shares its local files with the VM. If you open the File Sharing tab in Docker Preferences you’ll see a list of directories it shares, so you can mount files from any of these directories or sub-directories. /usr/loca/bin/ is not on the list and if you try to add it (or its parent, /usr/local/) it won’t do it saying that the path is reserved by Docker…

I’ll add a little hack to detect the /usr/local/bin installation on Macs, so the master copies the sensor app to the /tmp directory (one of the shared directories by default) setting the state path to the same location too.

Thanks for the reference @Ladicle! Wonder if it’s security related somehow. Doesn’t look like it’s limited to Mojave (I was able to repro it with an older version of Mac OS X (10.11)).
