$1 is supplied to all package scripts by rpm, and is the number of
packages that will be installed at the end of the transaction, thus it is
1 for new installation, 2 for upgrade (rpm first installes the new
package, then removes any files from the old package) and 0 for removal.
%{1} etc are the arguments given to the macro. So in your case, vdr ends
up being $name.

It helps to do 'rpm -qp --scripts mypackage.rpm' to see what rpm has done
to the script (replacing the macros).

It should work as you have it, otherwise maybe you need a 3rd argument
(shell)?
