Has anyone stepped forward to possibly shepherd this code into the tree? I am highly interested in this code and would like to see it incorporated into the base system (read: -CURRENT, before 5.2). After looking at the TODO, I realize that this patch isn't 100% yet, but can it be broken down into a smaller set of commits? Anyone doing virtual hosting would kill to have this functionality in FreeBSD right now. -sc -- Sean Chittenden _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
