In case this configuration option is defined, then an IMFS with a reduced
feature set will be the base filesystem (also known as root filesystem).

notes: |
In case this configuration option is defined, then the following
configuration options will be defined as well
* ${imfs-disable-chmod:/name},
* ${imfs-disable-chown:/name},
* ${imfs-disable-link:/name},
* ${imfs-disable-mknod-file:/name},
* ${imfs-disable-mount:/name},
* ${imfs-disable-readdir:/name},
* ${imfs-disable-readlink:/name},
* ${imfs-disable-rename:/name},
* ${imfs-disable-rmnod:/name},
* ${imfs-disable-symlink:/name},
* ${imfs-disable-utime:/name}, and
* ${imfs-disable-unmount:/name}.
In addition, a simplified path evaluation is enabled. It allows only a look
up of absolute paths.
This configuration of the IMFS is basically a device-only filesystem. It is
comparable in functionality to the pseudo-filesystem name space provided
before RTEMS release 4.5.0.
