(ie how do we implement the append access mode - and non-position-dependant read/write calls & seek call) -* Better error reporting for system calls that fail - -### Things not sure - -* VFS thread safety : is the design correct ? (probably) -* Cache architecture (called *pager*, after 4.4BSD terminology) -* Not enough tests! - -### Plans for the later future - -* Define a format for "packages", i.e. read-only filesystem images used for adding system - components or apps to the OS ; make sure to implement it in a way that does not waste - memory -* Module system for extending the kernel -* In userspace, simple Scheme-like scripting language -* POSIX compatibility layer, self-hosting OS -* The obvious stuff ;-) - ## Licence None of the source files have a licence header because it's cumbersome.
