Adding the GESBC-9302 File System to the Debian NFS Server

Now that the Debian NFS is operational, the GESBC-9302 file system can be

loaded into /armfiles. Then we can try to boot the GESBC-9302 directly from the

Debian using NFS.

The first task is to put a complete copy of the GESBC-9302 file system on the

Debian hard drive in /armfiles. The file system is supplied by Glomation on the

CD at /Linux/GESBC-9302/ramdisk.gz

I made a new directory, /armdisk, and copied the ramdisk.gz file from the CD to

/armdisk. Decompress using the gzip command: gzip –d ramdisk.gz

This produces a single file simply called ramdisk. The next step is to mount the

ramdisk on the Debian development PC. This is done by mounting it as a loop

device, as follows:

mount –o loop /armdisk/ramdisk /armdisk

If the mount command is successful you should be able to see the GESBC-9302

file system in /armdisk on your Debian machine. This sequence is shown in the

screenshot below:

Note that you must go out of the /armdisk directory, then come back in, to view

the files now mounted from ramdisk.

The files, however, are not yet captured to the Debian hard drive. But now it is

simply a matter of copying the /armdisk recursively to /armfiles.

cp –ra /armdisk/* /armfiles

DebDevel:/armdisk# ls

ramdisk

DebDevel:/armdisk# mount -o loop /armdisk/ramdisk /armdisk

DebDevel:/armdisk# cd /

DebDevel:/# cd /armdisk

DebDevel:/armdisk# ls

bin dev etc home lib mnt proc sbin tmp usr var

DebDevel:/armdisk#
