527 help
528 If you are experiencing any problems with the NTFS file system, say
529 Y here. This will result in additional consistency checks to be
530 performed by the driver as well as additional debugging messages to
531 be written to the system log. Note that debugging messages are
532 disabled by default. To enable them, supply the option debug_msgs=1
533 at the kernel command line when booting the kernel or as an option
534 to insmod when loading the ntfs module. Once the driver is active,
535 you can enable debugging messages by doing (as root):
536 echo 1 > /proc/sys/fs/ntfs-debug
537 Replacing the "1" with "0" would disable debug messages.
538
539 If you leave debugging messages disabled, this results in little
540 overhead, but enabling debug messages results in very significant
541 slowdown of the system.
542
543 When reporting bugs, please try to have available a full dump of
544 debugging messages while the misbehaviour was occurring.

549 help
550 This enables the partial, but safe, write support in the NTFS driver.
551
552 The only supported operation is overwriting existing files, without
553 changing the file length. No file or directory creation, deletion or
554 renaming is possible. Note only non-resident files can be written to
555 so you may find that some very small files (<500 bytes or so) cannot
556 be written to.
557
558 While we cannot guarantee that it will not damage any data, we have
559 so far not received a single report where the driver would have
560 damaged someones data so we assume it is perfectly safe to use.
561
562 Note: While write support is safe in this version (a rewrite from
563 scratch of the NTFS support), it should be noted that the old NTFS
564 write support, included in Linux 2.5.10 and before (since 1997),
565 is not safe.

567 This is currently useful with TopologiLinux. TopologiLinux is run

570 need its own partition. For more information see

586 The sysfs filesystem is a virtual filesystem that the kernel uses to

1031 If you only intend to mount files from some other Unix over the
1032 network using NFS, you don't need the System V file system support
1033 (but you need NFS file system support obviously).

1036 good portable way to transport files and directories between unixes
1037 (and even other operating systems) is given by the tar program ("man
1038 tar" or preferably "info tar"). Note also that this option has
1039 nothing whatsoever to do with the option "System V IPC". Read about
