During the home stretch of this semester, I'm putting priority on creating a standard image that will work on all our hardware. Well, not exactly, I'm creating an abstract definition of what our images should be, I'll be applying that abstract definition to three actual images (based on hardware platform) to fill our needs.
The first step in the process was writing a well-documented definition of what exact changes need to be made to the base Ubuntu install in order to make it suitable for our needs
I then installed Ubuntu on each of the three different hardware platforms (Dell 170Ls, Dell 210Ls, and 10 Dell Inspiron 1300s), followed the script laid out by the definition, and boom: I have an image for each hardware type.
Getting the SystemImager Suite working has taken quite a bit longer than I expected, so we're still depending on Symantec Ghost 8.0--in Unicast mode--for all our imaging needs.
We now have what it takes to complete setting up the final classroom (which, for some reason that escapes my ken, has both 170s and 210s in it).
Since I have not gotten a working classroom management suite on the new image yet, the original four classroom teachers do not want to be upgraded to it yet.
