So… after upgrading Fedora 18 installation to Fedora 19 (using DVD ISO image) via 'fedup' tool which was quite event-less* (not quite, read below); decided to upgrade second laptop running Fedora 17 to 19 directly using network (note that F17->F19 upgrade is not supported, IIRC).
Downloaded the latest f18 fedup noarch rpm (hey, it’s python!) from Koji directly and installed on F17 system. Did a 'fedup-cli --verbose --network 19'. After half an hour and around 2.0 GB of package downloads including third party ones, new ‘Upgrade’ boot entry is set up and reboot into it.
Boots into F19 upgrade plymouth screen… nothing happens – instead of progressing upgrade, system simply reboots after few minutes. After some head-scratching and trying to capture systemd errors, found the culprit to be a mount point entry in /etc/fstab with ntfs-3g file system – mount attempt was timing out and boot fails.
