pub fn refuse_managed(command: &Command) -> Option<ExitCode>Expand description
Refuse --managed where nothing can start a container.
The flag says “start a disposable managed container”. Only with and
configure do — they launch or point a client at a router, and starting one
is part of that. Everywhere else it started nothing and quietly meant
--local: a second, undocumented synonym whose own description promised
something it never did (issue #315). Saying so beats a silent second
meaning, and --local is the flag that was wanted.
