[Libguestfs] febootstrap 3.x use cases.

I'm confused! What use cases is the new febootstrap primarily intended for? I'm mainly trying to figure out if I'm trying to put a square peg into a round hole. What I'm looking into is using linux containers (LXC) either using libvirt or lxc-tools) to create jails for a web hosting type environment. I can see that in the long run btrfs has some nice features to help with this too. Is febootstrap really intended for this kind of use case? I can see two mechanisms that might work for what I'm trying to do: * Figure out how to create application containers around apache/whateverwebserver with a docroot and virtually no other filesystem. The down side to this is that it needs a lot of stuff added to the jail to make it work. * Use something like febootstrap or btrfs to create minimal filesystem roots for each hosted environment. This seems simpler if a little overkill. I'll probably ask over at the lxc lists and take a look at OpenVZ too. I'm mainly interested in finding out more about the intended use of febootstrap here.
