I did simple upgrades on both of my computers. Everything seems to be fine after using them the last 3 days.
Don't have any haxies, keep a fairly clean system. Made sure to repair permissions, run fsck, clear logs and caches and restart a time or two before installing.
Also repair permissions after install. Fsck requires a different instruction now that I didn't quite understand since journaling is activated by default with the install.
Is it now?
fsck -y -f
