MinorCowFs is not yet implemented.

The concept of MinorCowFs is the implementation of directory level copy on write as a composition pattern.
It is planned that MinorCowFs will have the folowing interface:

From an empty [[MinorCapFS]] directory, the 'raw' extended attribute will return a path like:
/mnt/minorfs/cow/raw/$RAWCAP . This path can be used as the target location for the creation of a 
symbolic link node, pointing to a location that is to be considdered a read only directory tree.

Ones the /mnt/minorfs/cow/raw/$RAWCAP symlink is created, the 'cow' extended attribute can be retrieved from it.
The 'cow' attribute will point to a path like /mnt/minorfs/cap/$COWCAP. This path will provide a RW directory tree,
where all updated files will be stored under /mnt/minorfs/cow/raw/$RAWCAP.
