# Setup users. To add a new user:
# 1. Add the name of the user to the list in the second-to-last line
# 2. Make sure that the git repo contains the key as "$USER.pub"
# 3. Make sure that the commit ("rev") contains the latest commit hash. If it correct, jump to step 7.
# 4. If you changed the commit, manipulate the sha512 entry by changing the first character from 0 to 1 or 1 to 0.
# 5. Run "nixos-rebuild build"
# 6. Wait for a message about an invalid hash and replace the hash in this file with the new one.
# 7. Run "nixos-rebuild switch"
# 8. Let the user login and change their password
