FreeBSD lacks a native docker (what prevents from fixing Isn't the whole point of docker to package applications in containers so that (among other simplifications) there was no need to support multiple versions of services in the same environment. One service, one container works just as well in jails as in docker, granted it's not as easy as writing a yaml file and watching a poorly understood swarm of thousands of containers spring to life and provide a load-balanced service, but it isn't hard especially with iocage templates. Personally I always run services in single service jails and have done for a lot longer than docker has existed. From what I can see docker offers very little advantage if what you need is one-off servers and you want complete control over what's on them and what they do. It offers huge advantages if you want to administer large load-balanced swarms of standardised components. > True, some of those disadvantages are fixable, but now the impression is > that FreeBSD is lagging behind.

Standard advice in Linux world regarding major version upgrades seems to be "Don't do it and if you do expect breakage". That is a *major* technological advantage. Regardless what is with the idea that one OS must be "better" than another - a Stilson is not better than a ring spanner, they are simply suited to different (but similar) tasks. -- Steve O'Hara-Smith <steve@sohara.org>
