Thank you Henry, that actually made me get one step further...

Now I'm getting something like this, since it appears the file system
of the initrd is readonly and coLinux initrd is not able to create the
lib directory. into defined root...

Installing modules for coLinux 2.6.22.18-co-0.8.0-SVN1038
Mounting cofs for vmlinux-modules.tar.gz

Trying to move old root to /initrd ... /initrd does not exist. Ignored.
Unmounting old root
Trying to free ramdisk memory ... okay

That was from the colinux console, this is from -v 3:

Results from file:

/opt/gobo-initrd: Linux Compressed ROM File System data, little endian
size 761856 version #2 sorted_dirs CRC 0x14ec9052, edition 0, 441
blocks, 283 files

It seems is quite a challenge get GoboLinux (which doesn't follow FHS)
to work under coLinux... too bad :-(

Thank you for your time and helpful assistance.
