+description: |
+  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
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_CHMOD`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_CHOWN`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_LINK`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_MKNOD_FILE`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_MOUNT`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_READDIR`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_READLINK`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_RENAME`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_RMNOD`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_SYMLINK`,
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_UTIME`, and
+
+  * :ref:`CONFIGURE_IMFS_DISABLE_UNMOUNT`.
+
+  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.
