The thing is, in my world all of these drawbacks you've listed on your own are unacceptable for production use, and almost each of them disqualifies the LXC separately, not mentioning all of them together. In addition to that, you've mentioned that your knowledge of jails is outdated, and I can confirm that, it is ;) Most of things you've listed as drawbacks for jails is no more true: they are hierarchical, they have their own network stack, they can be restricted with cpu/ram/swap usage, and so on. Of course, this is highly subjective, as everything else is - its cool that you can run Steam in LXC and I cant run it in jails, but running steam is not something I want and need to achieve, its security and separation of architecture blocks, and in this world, jails are 'better' technology. Keep in mind, this is not religious - LXC was my technology of choice to start with, but I had to drop it due its immaturity and issues. Will LXC fix all of this, I will probably switch in no time (probably, because of the surrounding features FreeBSD provides).
