An administrator should be able to put Keep configuration settings in a file.

Default location of Keep config file: /etc/keep.yml

Config file location can be changed with a --config option. (Note: interesting things may happen if the config file includes a "config" option. Consider explicitly forbidding this.)

Each entry in keep.yml is the name of a command-line option without the leading dashes, e.g. permission_ttl or volumes.

Keep rereads its configuration file upon receiving SIGHUP.
