Re:Re[2]: [coLinux-devel] Some problems....

Hello,

  No, without ISO FS the coLinux kernel won't be able to mount either
an ISO "file" or a CDROM.  You need to copy the contents of the ISO
image into an EXT2 or EXT3 filesystem.

  Ie;  assuming your ISO image is called "mycd.iso", then under some 
other Linux installation perform the following;


     # work in the /tmp dir (make sure you have at least 1.6Gbytes free
     # before you copy in the ISO image).
     cd /tmp

     # mount the old file system
     mkdir oldfs
     mount -o loop ./mycd.iso ./oldfs

     # make the new file system (I only have ext2 under RH7.2)
     dd if=/dev/zero of=./myfs.ext2 bs=1M count=800
     mkfs.ext2 -F ./myfs.ext2 

     # mount the new file system
     mkdir newfs
     mount -o loop ./myfs.ext2 ./newfs

     # copy the contents from the old to the new
     cd newfs
     cp -R ../oldfs/* .

     # sync and unmount the filesystems
     cd ..
     sync
     umount ./newfs
     umount ./oldfs


  The file "myfs.ext2" in the /tmp directory should then work as an
ext2 file system under the coLinux kernel.  If you have a newer 
OS to build it from, then make it an ext3 file system (replace the ext2
bits with ext3 in the above).

  Alternatively, wait until a newer version of the binary coLinux
release comes out, supporting ISO FS natively.


Hope that helps,
