I was not able to install the minimal system or at least I could not get it to run - probably I was not understanding how to run things. I reformatted the internal memory and installed the full easy debian. When I start the debian chroot, everything works OK. I freed up some space and was able to just barely install r-base. I would like to free up more space. Can I uninstall openoffice or iceweasal? Will this cause any problems?
