I must say that this virtualization sounds very promising in making the jail even more useful! And of course all the other avenues that are made possible with this. I guess the main/traditional question to ask first would be: This change adds abstraction, therefore it probably reduces performance - by how much? Thanks for the initiative Marko, I hope this will be seriously considered for inclusion (barring any negative side-effects of it). And I hope I'll have a chance to give it a test-drive soon! :) Cheers, /Johny To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
