Well, I just updated from 13.0 to 13.2 using freebsd-update. and at the second reboot I was dumped to a console, and X refused to start. I hadn't noticed much user stuff updated, so I did pkg update, pkg upgrade, still no X. After searching around I found that I'm certainly outside the 3 month window where packages are built against the old minor version, maybe I'm an edge case. So I built drm-510-kmod from ports, but it refused to install because drm-fbsd13-kmod still had files in the same place, and I had to remove that manually with pkg delete.
X and xfce are all working OK now, but am I being a bit picky if I suggest there is something missing from the upgrade instructions?
