The rollback state of this module doesn’t seem to be working correctly. This line “[[ -f $prev_files_tar ]]” always fails. This is a bash command not a shell command and since the dir-overlay module is using “#!/bin/sh” instead of “#!/bin/bash”, it does not work. Maybe it works on some machines, but…

Issues with dir-overlay Update Module rollback state

I will do.

Sure, but during my quick test, it seems the problem only appears for the root directory (to be confirmed )

Thanks @mirzak for the feedback and the suggestion, I’m going to test it and investigate more.
