 A great overview of building the Ubuntu root filesystem can be found [http://elinux.org/BeagleBoardUbuntu#RootStock:_Build_an_Ubuntu_root_file_system here].  This is the second time in the process where we don't compile something for ourselves (the first being the cross-compiler).  Rootstock downloads pre-compiled user space applications and libraries.  I am not too worried about this because these are not in the kernel space.  Rootstock is an Ubuntu supported ARM root filesystem builder, so I will trust that their user space binaries are up to par.
-Before we proceed, you will need to install rootstock and dctrl-tools (to process .deb bundles on the command line).  You will also need to create a new folder to hold the root filesystem and then cd into it.  Also, please note that '--fqdn beagleboard' specifies the fully qualified domain name is 'beagleboard'.  You may use any fqdn you prefer, and it does not restrict the root filesystem to a particular board type.  The root filesystem is not board specific and will work for any OMAP based system, and quite possibly any ARM based system.

 This will create x-load.bin in the working directory.  This file will need to be "signed", which essentially pre-pends the load address and length to the image.  A good source for a signing tool can be found at [http://code.google.com/p/beagleboard/downloads/list Google's Beagleboard Project download page].  You can download a pre-built "signGP" or download "signGP.c" to examine and build the source yourself.  To do so, save signGP.c in your xloader/mainline directory and enter the following.
   gcc signGP.c -o signGP
