NSA's Security-Enhanced Linux

I wonder what NSA's ulterior motive in developing an open-source "security-enhanced" version of linux. But this quote from the download page isn't too reassuring:

Warranty Exclusion

You agree that this software is a non-commercially developed program that may contain "bugs" (as that term is used in the industry) and that it may not function as intended. The software is licensed "as is". NSA makes no, and hereby expressly disclaims all, warranties, express, implied, statutory, or otherwise with respect to the software, including noninfringement and the implied warranties of merchantability and fitness for a particular purpose.

I wonder what "industry" the NSA's referring to there?
