MinorFs
MinorFs is a set of simple cooperating user space filesystems that provide a way to do (extreme) discretionary access control. The discretionary access control mechanisms provided by MinorFs allow for usage in new system design that adheres to dynamic POLA. At the core of the discretionary access control in MinorFs is the concept of the pseudo persistent process. Where in most access control mechanisms for filesystems the user defines the base level of granularity, MinorFs uses the pseudo persistent process. This has a very convenient side effect that next to being usable for the design and implementation of new systems that use dynamic POLA, it is also very suitable to allow legacy programs to protect their 'private' data from malware or buggy software running under the same uid they run as. One usefull example of this is private key storage and the ssh client.
