Upgrading to Fedora 16

Finally had some time to upgrade my Fedora 14 distribution to Fedora 16. I followed the YUM upgrade instructions on the Fedora website. Having never had good luck with odd Fedora releases, I will be skipping Fedora 17 for now and waiting for 18 instead. Overall, The Fedora 15 upgrade was smooth and the reboot of my dual-boot system was successful. However, the following Fedora 16 upgrade presented me with a blank GRUB screen after reboot even though I followed the instructions line by line. At the end, I had to create a Fedora 16 DVD, boot into rescue mode, re-run the GRUB setup commands again:
chroot /mnt/sysimage

/sbin/grub2-mkconfig -o /boot/grub2/grub.cfg
/sbin/grub2-install BOOTDEVICE
After dealing with the usual sound problems, the system was up and running with the dual-boot GRUB setup still intact. At this point, a couple of changes have come to my attention. There is a new systemd component that handles system services. Runlevels concept is replaced by targets instead. Read more at systemd documentation and cheatsheet page. In addition, the chkconfig and service command outputs seem to have changed.
