Here I collect some information about things I had to do to get various Linux environments working to my satisfaction. I use Linux inside of Virtualbox virtual machines. I have a few different virtual disk images that I use commonly between different Linux "computers", such as one for projects files, one for Denx ELDK files, and one for /opt software installs. Then each Linux has its own disk image for OS install.
