Description
RTEMS does not provide a 'rename' call in the file system ops table. The rename function in libcsupport links then unlinks a node. This how-ever does not work with file systems that do not support the linking of directories. This is common in all operating system so the directory is a directed acyclic graph (DAG) instead of it being an arbitrary directed graph (with loops). All operating systems I know have a rename system call and I suppose this is part of the reason why.
If a file system does not support hard linking of directories the rename libc call fails.
The solution is to add a rename call and update all existing file systems.
