Good, Portable "Virtual" Linux Distro?
Prof. Nix writes "I have been given the opportunity to redesign the Linux course for the community college I work for. This course will be taking students from the 'What's Lee-nux?' stage to (hopefully) Linux+ Certifiable in about three to four months. However, one issue I haven't solved is finding a semi-stable, highly portable, and readily accessible platform the students may pound on, and have root access, independently of their peers. The powers-that-be have already vetoed any sort of server environment accessible from off campus. We've already tried live USB drives, but we ran into many issues with non-supported hardware on students' home computers. So I'm left with the idea of virtual machines run from flash drives. My ultimate goal is to have some sort of portable system that students can use with equal ease on lab systems and personal laptops — regardless of hardware. Preferably this system would be installable on a 4GB flash drive and run an Ubuntu- or Fedora-derived OS. So I ask the people who have been in the trenches a lot longer than I — what distros should I look at?"
I teach at the community college myself, and find that installing the OS is a really important part of learning to use it (creating partitions, mount points, swap, etc...) and is one of the first part that makes it very different from most Windows installation processes. Doing the install on a USB stick could result in students killing the Windows partition on the disk if they botch the install and accidentally put it on the hard disk. (I've had it happen).
Using a VM host on the lab computers (either MS Virtual PC or VMWare; assuming that your lab PCs are Windows) and then allowing them to create the virtual disk on their 4GB (or larger) flash disks will give them the install experience (without risk of damaging the host system), and allow their install to be fairly hardware independent (assuming they have the same VM host on their home PC.)
This also allows them to use a normal, general purpose distro than a stick-oriented one, that is also likely to have better textbooks available. I know any text should be good enough for derived distributions, but for students having an out-of-the-box or off-the-iso experience can alleviate a lot of first-week frustrations, and gives them a better (vanilla) resource to consult when bad things happen.
Forgive my spelling from time to time. I'm often posting during short breaks.
Great idea. Make the students waste their time fucking around just getting the thing up and running so they can start studying while every day the quarter slips away more and more. A virtual image is a great idea - hardware incompatibilities can happen at any level of the system (kernel, X.org, HAL/DeviceKit/CUPS/SANE regressions, etc, etc), so I think a good working knowledge of Linux is probably a prerequisite to troubleshooting hardware incompatibilities. Let the students actually understand what the kernel is and how modules work before making them go fetch sources to compile kernel modules.
I don't think community college is what people mean when they talk about the ivroy tower.
