I upgraded our server to Fedora 16 from Fedora 14 recently, so I thought I’d continue my tradition of posting the solutions to the problems I encountered to help others.
Two major changes in Fedora recently increased the difficulty of this upgrade: the switch to grub2 from the grub legacy bootloader, and the switch to systemd from Upstart and SysV-style init.
I used the PreUpgrade method once again to reduce downtime and avoid burning a disc.
