That is likely a bit out of date. I probably have a newer version of the 
script, but I am currently using a utility I wrote in C++ that has 
extended capabilities. It would probably be a better fit. For one thing, 
it allows assigning multiple physical drives as a single virtual 
magazine. I don't believe the Bacula Wiki was around at the time I wrote 
the howto, so the original howto was posted to Bacula Users.

I can, however, release the C++ as open source as well, so in the near 
future I will put the C++ source for vchanger on Sourceforge. I will 
also put a newer version of the howto on the Bacula wiki. I'll post a 
note here when that is done.
