A little research revealed that these two messages should be disregarded. They give a frightening impression of imminent danger. If they really are harmless, I hope Apple fixes the bug asap.
Admittedly those "warnings", they are not "errors", give uninformed users pause, but if years of history is any guide, if and when Apple "fixes" those "bugs" they will simply be replaced by different "warnings" in the next update. My guess is the only long term "fix" will be a switch in Disk Utility to set the level of error reporting with the default being to report only uncorrected
errors and not warnings or information messages.
By-the-way, you are correct about running Disk Repair from the install disc, or from another boot volume, but permission repair
should be run from the normal boot drive, not from the install disc.
