I have CentoOS 5.4 x86-64 and every time I do yum install ... two versions of the same package are installed: one ending in .i386 and the other ending in .x86_64.
Is it nessesary to install .i386 versions given my OS is x86_64?
Have I just been wasting space by always installing both .i386 and .x86_64 versions of the same package?
