This week's techmail is Introducing Linux virtual containers with LXC. I played with LXC for the first time a little while ago when writing this tip, and it's pretty slick. It's not quite as feature-complete or as robust as OpenVZ, but it's very close. It also has some benefits over OpenVZ, like direct integration with the upstream kernel. LXC is something to watch; it would be extremely cool to see things like Firefox stuffed into an LXC application container in the future, so it can really only ever mess with specific files/directories. LXC is definitely something to keep an eye on.
