We sadly need Wine to install Type To Learn which is a 1.1 GB program on our netbooks. I resize the base partition to 6 GB and then boot into the generic file system and everything installs and runs fine. I can rebuild the image on the key (which is 3.2 GB so it must include the TTL info) and image another system and everything works fine as well. However if I boot into the -aufs file system and change a printer and try to build simple updates it creates a 1.1 GB simple update file because wine is storing the C-drive in a .win folder in the Home directory. This makes the simple update process really long, the restore process take a long time, and ends up making the key larger than 4 GB. I tried removing the .wine folder from the user.tar.gz archive but then when I applied the updates TTL didn't work correctly.
So I can either set the printers for each room in the -generic file system and have a different base image for each classroom (only 6 classrooms so not the end of the world), or figure out a way for the simple updates to not include the .wine folder and also not overwrite the .wine folder, or some other genius idea
