Symptom
Disk Utility Repair Disk Permissions, when started up from your Mac OS X Install CD, may erroneously report an issue with /private/var/db/netinfo/local.nidb/* . For example:
"Permissions differ on ./private/var/db/netinfo/local.nidb/[text]"
Note: The text that appears after "local/nidb" varies, but may include "/Store.288" or "/Clean".
Solution
The message is not accurate but is not a cause for concern.
