Rewrite the Persistent Storage settings in Python
persistence-setup was written in Perl and, looking at the Git history, it might have prevented other people than intrigeri to do significant changes to it. I could only spot @segfault adding a feature in #17136 (closed).
It's an application that is here to stay, one of the first steps in the user journey, and in need of UX improvements.
I'm hoping that rewriting it in Python might also us to reduce the bus factor and improve it more rapidly.
While rewriting to Python, we'll do #15142.
