Comment 2 for bug 1731389

This bug can only be reproduced and classic where both sudo and trusted launcher controllers can be used.

When providers are installed system wide (normal install from a ppa), pkexec is preferred over sudo.
The plainbox trusted launcher is the used to run jobs as root.

But it needs to know/discover all jobs as only job checksums are used for security reasons.
Problem is that siblings jobs were not added to this list.

The linked MR proposes a fix for just the trusted launcher.
