Fixed In Version: file-5.04-12.el6
Doc Type: Bug Fix
Doc Text:
Previously, the file utility did not contain a "magic" pattern to detect the swap signature on Itanium microprocessors. As a consequence, the file utility was unable to detect the signature. This update adds the missing "magic" pattern, and the swap signature on Itanium microprocessors is detected as expected.
