The above referenced bug seems to be a really big deal on F10 upgrades.
The problem is that swap files never get unmounted, so the filesystems
they reside on never get unmounted, so migrateFilesystems fails. The
attached patch corrects this by adding support to just unmount swap
files. If we come to some sort of agreement on this patch, I'm in favor
of including it in an updates.img.
