I would advise against changing init. If you want to fetch libraries
from different portions of a file system or from different file systems,
I recommend you to create a more sophisticated version of fs_rom, which
does not use a single file-system session but multiple. Let me call it
"multi_fs_rom" for now. The ROM modules will still be requested by their
plain names. The multi_fs_rom service will scan the search locations for
files with the supplied name and hand out the file content as a
dataspace. This way, you can keep libraries and executables at arbitrary
places.

To let CLI monitor use your multi_fs_rom service instead of obtaining
ROM modules from core, add the following line at the beginning of the
routing configuration of cli_monitor:

  <service name="ROM"> <child name="multi_fs_rom"/> </service>

It looks like it is time to develop your first ROM service. :-)

Cheers
Norman
