Hi, I just installed CentOS 5.4 on a 64bit-server. It's the first time I work with this sort of hardware. Doing rpm -qa | sort | less shows that most of the packages seem to be installed twice: once for i386 architecture, and then again for x86_64. Is this normal? Or did I mess up something during install (thought I wouldn't know what)? Niki

Some programs (32bit ones) expects to find 32bit libraries, so just to be on the safe side (and a little bit lazy),and if I have the options, I install for both architectures. Regards mg.
