-Please make sure that the process ends without errors. If there are no errors, at the end of the ''saving'' process, you will have disk image file with the name: ''"bob-node-sdr2-lg1.sb1.cosmos-lab.org-2013-02-06-14-16-23.ndz"'' in the directory ''"/export/omf/omf-images"'' on the machine with the host name ''"frisbee"''. These information are all provided in the output displayed above.

 You can then reload this disk image on a node (or nodes) using the ''omf load'' command.

+==== Working with the saved image ==== #files
+
+Images are treated as standard linux files. That means that you can:
+* check that they have a nonzero size `ls -al imagename`
+* Rename them `mv imagename imagenewname`
+* Delete them `rm imagename`
+* set permissions `chmod 600 filename`
+* set user and group `chown username:groupname filename`
+
+When you use OMF load, the `-i` flag refers to a file name in this directory. It obeys linux file permissions, so if you want to keep other people from loading your image, ensure that it doesn't allow group or everyone read permissions.
