Hi All

Iam a beginner/Learner in this field.

I have  Linux running on an intel x86 machine with cross development
environment.
I want to host 74xx file system  with Xfree86 and library support  on the
intel machine.

I will boot the file system using NFS to the 74xx system.

How to create/extract the file system with xfree86 support from fedora file
system  ?


Please help me on the above

Thanks in advance

I'm not sure if Fedora Linux has a Live CD that you can download for PPC =
machines.  We used an Ubuntu (Live) CD for our setup.  In our case the =
CD is bootable and contains a file called filesyste.squashfs that is a =
full desktop root filesystem with Xorg, all compiled for PPC.  You wont =
be able to unpack the squashfs file on your x86 Host because of the byte =
ordering, so you need to use your PPC target to do the work.

Mount the CDROM iso image on your x86 Host and then export this via NFS =
to your PPC target
  Host# sudo mount -o loop -t iso9660 ubuntu-6.10-desktop-powerpc.iso =
/mnt/
  Host# sudo mkdir /opt/ubuntu
  Host# sudo vi /etc/exports
    /mnt 192.168.0.0/255.255.255.0(rw,no_root_squash,sync)
    /opt/ubuntu 192.168.0.0/255.255.255.0(rw,no_root_squash,sync)

Use the Target to mount via nfs the Hosts /mnt/ directory that you =
exported, then mount via loopback the filesystem.squashfs and copy the =
contents back to the Host's nfs exported /mnt/ directory.

  Target# mount host_ip_address:/mnt/ /mnt/host
  Target# mount /mnt/host/casper/filesystem.squashfs /mnt/squashfs
  Target# mount host_ip_address:/ubuntu/ /mnt/ubuntu
  Target# cp -a /mnt/squashfs /mnt/ubuntu

I'm writing this from memory, so the above commands may be incorrect but =
the general idea and flow should be OK.
