Is VServer better/worse than Jail/Containers?

• You be the judge.

• Vserver is for linux only.
• vserver has a not easily measurable overhead
• vserver uses only a few K per context overhead, plus memory used by processes
• vserver can share binaries and libraries between systems, so vservers running similar daemons (or even C libraries) don't consume extra memory! And this is secure, and even fairly transparent with mad-cow!
• bind mounts can map parts of filesystem from one vserver to another!
