One great thing about Linux is that you can transplant a hard disk from a machine that runs a 32-bit AMD XP processor into a new 64-bit Intel Core 2 machine, and the Linux installation will continue to work.
However, if you do this, you'll be running a 32-bit kernel, a C library, and a complete system install on a processor that could happily run 64-bit code.
The warning was ominous, along the lines of "don't do this." I dismissed the warning; the upgrade proceeded, and I rebooted the virtual machine as normal.
Everything still seemed to work in the virtual machine after the cross-grade.
Supported Fedora versions: Node Version Manager is a bash script used to manage multiple released versions.
It allows you to perform operations like install, uninstall, switch version, etc.
With that success, I then moved on to the real thing: cross-grading a real live system.
After I selected the option to upgrade an existing Linux installation, the installer warned me that my existing install and the DVD were for different architectures.
I wanted to see if a cross-grade was feasible at a whole distribution level.
A disclaimer: changing the architecture of your Fedora installation from 32 to 64-bit isn't recommended or supported in any way.
is available from the Node Source Enterprise Linux and Fedora binary distributions repository.
Note that the packages for EL 5 (RHEL5 and Cent OS 5) depend on the EPEL repository being available.
