Just remembered: If you're wanting to bi-pass large parts of the Ubuntu OS like this, you may just want to use the "riscv-disk-image" ( http://dist.gem5.org/dist/v21-2/images/riscv/busybox/riscv-disk.img.gz), an example usage of which can be found in "configs/example/gem5_library/riscv-fs.py":
``` ./build/RISCV/gem5.opt configs/example/gem5_library/riscv-fs.py ``` This disk image is based on BusyBox, which is very light-weight. The source for building this image is found here: https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/riscv-fs -- Dr. Bobby R.
