    5  *  Make the path evaluation function common to all filesystems. The current mechanism requires a lot of duplication of code into all filesystems (that contains C string manipulation, making it even worse), requires a deep understanding of the filesystem infrastructure and makes implementing new filesystems a lot more difficult and frustrating than it should be. RTEMS should handle the mount point decoding, and only call into a particular filesystem when it is actually accessed. RTEMS should provide paths relative to the mount point of the particular filesystem.

     6Please ask on the list about this topic. Some of this work has been completed.

    68 *  Optional: RTEMS might also remove ".." and "." from the path, as well as extra "/"?
    79 *  This mechanism also removes the implementation of the mount and unmount calls in each filesystem, which further reduces the complexity of writing a new filesystem. These calls are sometimes left over for years, e.g. in the MSDOS filesystem, so this is a real issue.
