Thanks for your reply Corona688.
What I wanted to mean with standard arborescence was actually:
The system.tgz contains the integrality of the filesystem.

Now that you are talking about tftp, here is what I found on the PXE server:

Code:

santiago$ ls -AlR tftpboot/
tftpboot/:

drwxrws--x 3 root admins      4096 2009-01-23 17:35 debian-installer

drwxrws--x 2 root admins      4096 2009-01-23 17:36 pxelinux.cfg

-rw-rw-r-- 1 root admins      87 2009-01-23 17:36 ndtv.txt

tftpboot/pxelinux.cfg:
total 4
-rw-rw-r-- 1 root admins 821 2009-01-23 17:36 default

Is there any chance I can put that on the usb key?
But where? And how do I make it bootable?

switch_root

SWITCH_ROOT(8)						       System Administration						    SWITCH_ROOT(8)

NAME

       switch_root - switch to another filesystem as the root of the mount tree

SYNOPSIS

       switch_root [-hV]

       switch_root newroot init [arg...]

DESCRIPTION

       switch_root moves already mounted /proc, /dev, /sys and /run to newroot and makes newroot the new root filesystem and starts init process.

       WARNING: switch_root removes recursively all files and directories on the current root filesystem.

OPTIONS

       -h, --help
	      Display help text and exit.

       -V, --version
	      Display version information and exit.

RETURN VALUE

       switch_root returns 0 on success and 1 on failure.

NOTES

       switch_root  will  fail	to  function if newroot is not the root of a mount. If you want to switch root into a directory that does not meet
       this requirement then you can first use a bind-mounting trick to turn any directory into a mount point:

	      mount --bind $DIR $DIR

SEE ALSO

       chroot(2), init(8), mkinitrd(8), mount(8)
