Upgrade from 32-bit to 64-bit Fedora Linux without a system reinstall

Filed under
Linux

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. You'll waste even more resources if your new machine has 4GB or more of system memory, and you'll be forced to either not use some of it or run a 32-bit Physical Address Extension (PAE) kernel. Cross-grading to the 64-bit variant of your Linux distribution can help you use your resources more wisely.

This happened to me with a Fedora Linux installation, and I finally decided to migrate. Over the years, I've talked to Fedora enthusiasts and Red Hat employees at Linux conferences about doing a cross-grade to 64-bit. I generally heard one solution: reinstall. However, I like to reserve this approach for when a critical number of system disks fail at once and I have absolutely no other option. I wanted to see if a cross-grade was feasible at a whole distribution level.

A Seat at the Big Kids’ Table at Ohio LinuxFest

Ohio LinuxFest isn’t just another excuse to travel. It’s a means for us to fulfill ourselves, and to get honest, tangible feedback for what we do and for what others are doing. It’s a place where ideas are sounded, bent, crumpled and turned until they either come out of the crucible perfect…or useless. That’s what our gatherings are about. They are about excitement and promise. They​ are about making sure the next generation has a real chance to put the first human footprint on Mars. They are a chance to insure they have the tools and the curiosity to take something apart and then make it better. This next generation will cure diabetes; they will make cancer an inconvenience and not a death sentence. Read more

OpenStack Juno is out, Debian (and Ubuntu Trusty ports) packages ready

This is just a quick announce: Debian packages for Juno are out. In fact, they were ready the day of the release, on the 16th of October. I uploaded it all (to Experimental) the same day, literally a few hours after the final released was git tagged. But I had no time to announce it. This week-end, I took the time to do an Ubuntu Trusty port, which I also publish (it’s just a mater of rebuilding all, and it should work out of the box). Here are the backports repositories. For Wheezy: deb http://archive.gplhost.com/debian juno-backports main deb http://archive.gplhost.com/debian juno main For trusty: deb http://archive.gplhost.com/debian trusty-juno-backports main Read more

Video: Systemd the Core OS (no coughing)

There has been so much negative stuff about systemd on teh Interwebs lately. It is so sad. Quite a few distros picked systemd because they liked a lot of the features it has. Why do the people who like systemd actually like it? Sure, if you look hard enough, you can find those answers... but I remembered a video where the man himself explains it. Read more
