If you have just arrived at this page, then you might want to start with Solaris 10 zones: a working example and Solaris 10 zones: resource types posts. Today I’ll tell you about root filesystem models for non-global zones in Solaris.
Two filesystem models in Solaris 10 zones
As you probably know, there are two such models in Solaris 10: sparse root and whole root. The former approach means that the newly created non-global zone’s root filesystem will only partially consist of actually copied into it packages and files, the rest will be inherited from the global zone. Such a model needs approximately 100Mb of disk space per zone, which is obviously much less than a full Solaris 10 installation, which happens in a case of a whole root approach. I’ve already mentioned this earlier.
