Then your conf idea sounds good.

A different idea might be to have three subs like this:

my @alloptions=();
my @allOS=();

sub add_OS {
# add an operation system to the configuration matrix
  my $os= shift;
  push @allOS, $os;
  foreach my $opt (@alloptions) {
    calculate_parameter($os,$opt); 
  }
}

sub add_option {
# add a configuration option to the configuration matrix
  my $option= shift;
  push @alloptions, $option;
  foreach my $os (@allOS) {
    calculate_parameter($os,$option); 
  }
}

sub calculate_parameter { 
# calculate the option parameter in a specific OS
  my ($os, $option)= @_;
  ...

Creating and filling the matrix is automatically done by calling add_OS and add_option for every os and option.
