The script will always get them right, whereas humans (the author of this commit included) generally will not.

To update it, run `scripts/genfiles.sh` +which will regenerate it from the output of `git ls-files`. Any +changes you made will be lost. This script uses uses Git's index to +generate the list, so you need to use `git add`, `git rm`, and `git mv` +to ensure that Git knows about your changes. It is not necessary to +commit the changes. + +It is recommended that you add a Git pre-commit hook that calls +`scripts/pre-commit.sh`. This updates the `file-list.mk` files +for you, so that each commit always includes the correct +`file-list.mk`. Sadly, Git does not run the pre-commit hook +during rebases, so if you rebase you should use the script +`scripts/git-rebase` instead of `git rebase`. It tells +Git to run `scripts/pre-commit.sh` after each commit and then +calls `git commit --amend` to fixup the commit if needed. + By default, `make run` runs the VM in Cloud Hypervisor, to match the Spectrum environment. You can also add `VMM=crosvm` or `VMM=qemu` to your command line to run the VM in a different VMM.
