pub fn run_from_args(extra_args: Vec<OsString>) -> Result<()>Expand description
Entry point when invoked as a hidden cfsctl composefs-info subcommand.
extra_args contains everything after the composefs-info token as
captured by clap’s trailing-var-arg mechanism. A synthetic argv[0] is
prepended so that Cli::parse_from produces the same help text / error
messages as the standalone binary.
