StartOS 0.4.1.2 adds verification of OS and service updates against trusted developer keys

Start9 announced the Trusted Keys mechanism in StartOS 0.4.1.2: every operating system and service update is checked for a signature from developers you trust. If an update is not signed by any of the keys you have chosen, StartOS stops the installation and shows a warning. The operator decides which developers to trust.

Actions to take

If your Bitcoin node runs StartOS: update to 0.4.1.2 so that OS and service updates are verified by signature, and set the group of developers you trust. After that, updates not signed by them will be stopped with a warning. If this version is already installed and your trusted keys are chosen, no action is needed.
