That might not have been shipped with the device.
That might have been put on the device by the factory-only, production line, Q.A. firmware build that you installed in order to jail break it.

The name is misleading.
There is a FUSE system on the device, it is the fuse layer on top of /mnt/us that actually gets exported to USB driver.
But as long as it is running (or anything is running on /mnt/us) the export over USB can not be made.
Which might be part of its reason for being.

The way you wrote your post made it read as if you made the discovery while preparing to jail break it, not after you did.

And yes, the Kindle system is capable of NFS (both client and server).
You can find threads here on the subject.
The Kindles can also do a network boot from NFS in the initramfs system (before flash gets mounted).
Ah, it also does NBD
You can find some posts here where people played with swap over NBD (which really isn't very stable - that arrangement is subject to a deadlock)
OH, and also CIFS (Windows networking).
You can find posts/threads here on that also.

This is how you learn what filesystems the kernel is built to support:
Code:
[root@kindle us]# cat /proc/filesystems
nodev   sysfs
nodev   rootfs
nodev   bdev
nodev   proc
nodev   debugfs
nodev   sockfs
nodev   pipefs
nodev   anon_inodefs
nodev   tmpfs
nodev   inotifyfs
nodev   devpts
        ext3
        ext2
        ext4
        cramfs
        squashfs
nodev   ramfs
        vfat
        msdos
nodev   unionfs
nodev   nfs
nodev   nfs4
nodev   mqueue
nodev   rpc_pipefs
nodev   fuse
        fuseblk
nodev   fusectl
That is from 5.3.7.3, so of course, 5.9.something may be different.
Hmm...
I don't see CIFS on that list -
Oh well, I will not worry about it - this is just a quick example.
