Here's a probably dumb question but the answer may save me a lot of time: I'm currently running bind 9.3.4 on CentOS 4.4, which is a Red Hat clone. The current OS installation is 32 bit. If I upgrade to 64-bit CentOS (v5), will I need to recompile BIND or will it run fine as a 32 bit binary? Does BIND even care? Thanks!
