PostmarketOS 25.06: "the one with systemd"

The postmarketOS project,
which creates a Linux distribution for mobile devices, announced
it was working on adding a version with systemd last March. That day
has arrived with the announcement
of version 25.06:

We considered supporting an upgrade from OpenRC to systemd in our
upgrade script, but then decided against it as such an upgrade path
might introduce its own bugs and we would rather spend the time
improving other parts of postmarketOS. So for this one-time scenario
we ask you to please reinstall postmarketOS to get from OpenRC to
systemd. Thank you for your understanding!
