## @defgroup pseudomodule_vfs_auto_format vfs_auto_format
## @brief Format mount points at startup unless they can be mounted
##
## When this module is active, mount points configured through the @ref
## pseudomodule_vfs_auto_mount module that can not be mounted at startup are
## formatted and, if that operation is successful, attempted to mount again.
##
## Beware that this may be a harmful procedure in case a bug that corrupts a
## filesystem coincides with a bug that sends the device into a reboot loop.

## @defgroup pseudomodule_vfs_auto_mount vfs_auto_mount
## @brief Mount file systems at startup
##
## When this module is active, mount points specified through
## @ref VFS_AUTO_MOUNT are mounted at their designated mount points at startup.
## These mount points can be specified by the application, or are provided by
## some boards if the @ref pseudomodule_vfs_default module is active.
PSEUDOMODULES += vfs_auto_mount
## @defgroup pseudomodule_vfs_default vfs_default
## @brief Enable default assignments of a board's devices to VFS mount points
##
## When this module is active, boards with additional flash storage will
## automatically mount (and possibly format, if @ref
## pseudomodule_vfs_auto_format is enabled) their flash devices with a file
## system that is common for that board (or at least common for this board
## within RIOT).
##
## Boards will generally mount to `/nvm` unless they have several storage
## backends.
