64 bit systems

On a 64bit machine, you occasionally need both the x86_64 packages and the i386 (i.e., 32 bit) packages. As best we currently understand it (folks who are more into this, please pitch in, or at least dig up good references for more reading and link those in), the difficulty arises when you start out needing a package which is a 32 bit package. That package may break if it doesn't have other 32 bit packages to depend on. Yes, of course these things really ought to be interchangeable, but let's remember that this is open source software. There's a real, meaningful trade-off between hard encapsulation and rate of progress. Allowing for greater flexibility encourages a much richer growth pattern. And you aren't paying for this stuff, so cope smile and install both sets of packages....

Some packages to be aware of specific to 64 bit systems

  • mcelog - a daemon that collects and decodes Machine Check Exception data on x86-64 machines
  • microcode_ctl - Tool to update x86/x86-64 CPU microcode
