Well I should have qualified it with 'docker containers'. But yeah, those that have been around long enough in Linux container land have all dealt with vserver, openvz, lxc, etc, and all of those carried around this 'entire copy' of an OS, per container (ignoring vserver's vhashify). Docker helps you to spin up N containers running all sorts of applications based on the single master image.

Docker, whether your view is good or bad, brings something more than just another container implementation to the table...
