Note that the vnode file code is moderately broken, with regard to locks and GEOM and all that. To avoid lockups if you do this, make sure each 5G file lives in its own subdirectory, and does not share a subdirectory with another file that is also being used as a device. Otherwise, it's fairly easy to lock up, and in fact, the cron job for the security notification's "find" in the main vs. the jailed system will cause it to lock hard. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
