ammkvtapes.sh

As I mentioned in another thread some minutes ago, I have done somegeneralization-work on a script by Gene Heskett, which he sent to meback in 2004.

This script is intended to help generating the necessary structures fora vtape-setup, creating the various virtual tapes and slots etc.

I dug up my latest version and post it here without further testing,please only use it after you have read the code.

Create the config-dir for your new vtape-config and set the parametersin amanda.conf accordingly.

After that you run

ammkvtapes.sh <newconfig>

and the script should read the necessary parameters out of your amanda.conf.

As always, patches welcome.
Thanks again to Gene for the first script,

Stefan.
