[Jul 2024] Updates to Scripts

Since the scripts in this repository were written in 2020, some external changes have caused minor breakage (such as signed links expiring and the QEMU git mirror changing locations). For anyone still looking to reproduce the results from the 2020 NSDI paper, please apply the following diff to the repository and then follow the instructions in README.md (note that the correctly loop device number will depend on however many loop devices are already in use on your system. If you're using snapd, then this can be quite a few):
