When booting the upgrade.img produced by fedup (new Fedora upgrade tool) and systemd-194-1.fc18, a systemd failure during boot causes systemd to crash, preventing the upgrade process. Error message on console: Assertion 'prefix' failed at src/shared/path-util.c:269, function path_startswith(). Aborting. The fix is already in upstream systemd git: http://cgit.freedesktop.org/systemd/systemd/commit/?id=bcbd5405b1b6d9d219259e3be2c3ec4d92812bcb This fix is definitely present in systemd-195-4 (upgrade.img built with 195-4 doesn't crash) but any version with the needed fix would solve the issue.
Proposing as a blocker for F18 beta due to violation of the following F18 beta release criterion [1]: For each one of the release-blocking package sets ('minimal', and the package sets for each one of the release-blocking desktops), it must be possible to successfully complete an upgrade from a fully updated installation of the previous stable Fedora release with that package set installed, using any officially recommended upgrade mechanisms. The upgraded system must meet all release criteria. [1] http://fedoraproject.org/wiki/Fedora_18_Beta_Release_Criteria
