I am not sure if this question was already asked or not, but can you please tell me or point me to links where I can find what are the benefits or problems to have Sparse vs. Whole Root Zones?
Here is what I have so far, please correct me if I'm wron on any of them. Whole Root Zones * Each zone is assigned its own root file system and cannot see that of others * A zone can be created as a whole-rootzone > The zone gets its own writable copy of all Solaris file systems * Advantages of a whole root zone > installation of software such as WebSphere MQ v6.0 is easily acomplished since MQ must be installed into an environment where /opt and /usr are writable. > portability Sparse Zones > The default file system configuration is called a sparse-rootzone > The zone contains its own writable /etc, /var, /proc, /dev > Inherited file systems (/usr, /lib, /platform, /sbin) are read-only mounted via a loopback file system (LOFS) > /opt is a good candidate for inheriting * Advantages of a sparse root zone > Faster patching and installation due to inheritance of /usr and /lib > Read-only access prevents trojan horse attacks against other zones > Libraries shared across all zones reducing VM footprint _______________________________________________ zones-discuss mailing list [email protected]
