[20050413] Protecting harddisk security
Matthias Drochner has implemented a 'security' command for atactl(8) to query and esp. freeze the status of modern harddisk's security extensions. This prevents evil intruders (and potential viruses, but that's not a real problem in NetBSD today :-) from scrambling the harddisk password and thus making the harddisk unusable. See this slashdot article on how virus writers may abuse this security feature that many(?) modern harddisks have on other, non-NetBSD, platforms.
