you can enable debugging messages by doing (as root):

The only supported operation is overwriting existing files, without

changing the file length. No file or directory creation, deletion or

renaming is possible. Note only non-resident files can be written to
|
|
so you may find that some very small files (<500 bytes or so) cannot

be written to.

While we cannot guarantee that it will not damage any data, we have

so far not received a single report where the driver would have

damaged someones data so we assume it is perfectly safe to use.

Note: While write support is safe in this version (a rewrite from

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

export internal kernel objects, their attributes, and their

relationships to one another.
|

Users can use sysfs to ascertain useful information about the running

kernel, such as the devices the kernel has discovered on each bus and

which driver each is bound to. sysfs can also be used to tune devices

and other kernel subsystems.

Some system agents rely on the information in sysfs to operate.

/sbin/hotplug uses device and object attributes in sysfs to assist in

delegating policy decisions, like persistently naming devices.

sysfs is currently used by the block subsystem to mount the root

Coda is an advanced network file system, similar to NFS in that it
|
|
enables you to mount file systems of a remote server and access them
|
|
with regular Unix commands as if they were sitting on your hard
|
|
disk. Coda has several advantages over NFS: support for
|
|
disconnected operation (e.g. for laptops), read/write server
|
|
replication, security model for authentication and encryption,
|
|
persistent client caches and write back caching.
|
|
|
|
If you say Y here, your Linux box will be able to act as a Coda
|
|
*client*. You will need user level code as well, both for the
|
|
client and server. Servers are currently user level, i.e. they need
|
|
no kernel support. Please read
|
|
<file:Documentation/filesystems/coda.txt> and check out the Coda
|
|
home page <http://www.coda.cs.cmu.edu/>.
|
|
|
|
To compile the coda client support as a module, choose M here: the
|
|
module will be called coda.

If you say Y here, you will get an experimental Andrew File System
