The chmod -R was pretty fatal, it removed -x from directories... Also, 440 is not ok, as some of our tools like to open for writing and fail if they cannot (possibly unnecessarily so, but that's another issue for later!).

There should be two parts to this fix:

* alias taler-exchange-keyup in ~/activate to something that first runs they keyup command and then fixes up permissions
* add some logic in taler-deployment-start to check if the permissions are correct, and then give a nice warning

This "task" has no context.

> Deployed keys

Deployed where?

> should be assigned to the 'demo' group

Well that's probably on taler.net right? Okay, and this is something root user can do.

> and only have read/write permissions.

For the group only?

> The attached script addresses this

What script?

> should be applied and tested.

Applied in what context? As in, by which user on which server? This may be answered by answering the above.

Deployed on taler.net, using the scripts in deployment.git/bin/, which for the demo are (to be) run manually following the procedure in the onboarding/developer manual as per the demo upgrade procedure, which is documented here:
 https://docs.taler.net/developers-manual.html#demo-upgrade-procedure

I've already fixed this out of necessity while doing a new demo deployment about 3 days ago:
