Switching my laptop to Ubuntu took much less time and effort than I thought it would take. I couldn’t resize my existing partitions, so I formatted my data partition and made my swap partition smaller. This gave me about 6.5GB of space for the base Ubuntu system. My /home directory was already on a separate partition, and the other partitions had my installations of Microsoft Windows and Redhat Enterprise Linux.
Reusing my /home partition made it really easy to get up and running. I’ve also symlinked a few shared directories such as /usr/src and /usr/local. End result: a system that’s pretty much like my RHEL system, but much more current.
