The automounter provides an OS-internal mechanism for automatically
|
|
mounting and unmounting removable media as the media is inserted and
|
|
removed. See include/nuttx/fs/automout.h for interfacing details.
|

config FS_AUTOMOUNTER_DEBUG
|
|
bool "Auto-mounter debug"
|
|
default n
|
|
depends on FS_AUTOMOUNTER && DEBUG_FEATURES
|
|
---help---
|
|
Normally, the auto-mounter will generate debug output when sub-system
|
|
level file system debug is enabled. This option will select debug
|
|
output from the logic related to the auto-mount feature even when file
|
|
system debug is not enable. This is useful primarily for in vivo
|
|
unit testing of the auto-mount feature.

config DISABLE_PSEUDOFS_OPERATIONS
|
|
bool "Disable pseudo-filesystem operations"
|
|
default y if DEFAULT_SMALL
|
|
default n if !DEFAULT_SMALL
|
|
---help---
|
|
Disable certain operations on pseudo-file systems include mkdir,
|
|
rmdir, unlink, and rename. These are necessary for the logical
|
|
completeness of the illusion created by the pseudo-filesystem.
|
|
However, in practical embedded system, they are seldom needed and
|
|
you can save a little FLASH space by disabling the capability.

config PSEUDOFS_SOFTLINKS
|
|
bool "Pseudo-filesystem soft links"
|
|
default n
|
|
depends on !DISABLE_PSEUDOFS_OPERATIONS
|
|
---help---
|
|
Enable support for soft links in the pseudo file system. Soft
|
|
links are not supported within mounted volumes by any NuttX file
|
|
system. However, if this option is selected, then soft links
|
|
may be add in the pseudo file system. This might be useful, for
|
|
to link a directory in the pseudo-file system, such as /bin, to
|
|
to a directory in a mounted volume, say /mnt/sdcard/bin.
