CentOS uses */lib64 and */lib as opposed to Debian based distributions that use a chroot for 32 bit applications. > How is Upstream package selection comparing 32-bits and 64-bits > editions? >From what I can see on the beta, everything available for 32 is available for 64 bit. I run a fully 64 bit machine for a while (before I had to send my machine back for fixing) and it seemd to work just fine. You will have some problems with closed source software such as flash, as they're compiled for 32bit. I know there are ways to get around it (running a 32bit version of the browser or running a "proxy" app that allows you to use 32bit plugins) but I haven't used any of them as I was trying to run a "pure 64bit" machine. > I want to figure out if I should use CentOS/RHEL 5 x86_64 in desktop > environment. I used it and was quite happy with it. In my system (AMD X2) it seemed more responsive than my previous machine (Core Duo) but I do think that much of that difference is due to hd speeds.
