appl-config-option-type: feature-enable
appl-config-option-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).
appl-config-option-index: []
appl-config-option-name: CONFIGURE_USE_DEVFS_AS_BASE_FILESYSTEM
appl-config-option-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.
